A Smaller, Bigger Hammer: Glock 29 SF Review

by Greg Rodriguez   |  February 14th, 2013 15


A few months ago, I got a note from Glock asking if I was interested in reviewing the 10mm Model 29 SF. The firm’s PR rep asked if I’d take a look at it from a hunting angle since the 10mm is my favorite cartridge for handgun hunting. I thought it was an odd request because the G29 is a stubby, little auto pistol with fixed sights and a 3.78-inch barrel. But after shooting it several times over the last few months, I have to say the pocket-sized G29 SF definitely has a place in the field.

SF Means Short Frame
The Model 29 SF’s “SF” designation stands for short frame. Glock’s .45 ACP Model 21 and the full-sized Model 20 10mm have notoriously large grips. The SF variants reduce the circumference of the grip by reducing the length of the grip between the backstrap and the trigger. The result is a smaller grip that makes Glock’s most powerful auto pistols more appealing to shooters with average-sized hands. Please note the word “average.” If you have small mitts, even the SF variant is probably still too big for you.

Like all Glocks, the G29 is a polymer-framed pistol. The frame has thumbrests molded into both sides of the grip and two finger grooves in the frontstrap with checkering in between the grooves to help maintain a secure grip under the little blaster’s significant recoil. The front of the frame has an integral accessory rail that accepts lights and lasers, and a reversible magazine release is located on the grip just aft of the trigger guard. The pistol comes with two 10-round, polymer magazines, and it also accepts the G20’s 15-round mag.

My sample gun’s trigger breaks at 5 pounds, 6 ounces. The striker-fired pistol uses Glock’s classic “Safe Action” trigger system, which is made up of three independent, automatic safeties. The proven safeties will not allow the pistol to fire no matter how hard it strikes the ground. Moving the trigger completely to the rear deactivates all three safeties simultaneously. They engage again when the trigger begins its forward movement. It is a safe design, but remember that the only release is on the trigger face. Always carry any Glock in a holster that completely covers the trigger for safety’s sake.

The SF has a hammer-forged, 3.7-inch barrel with hexagonal rifling. The machined steel slide is, understandably, a bit beefier than the slide of 9mm Glocks. The G29 slide wears Glock’s almost indestructible finish and is fitted with fixed sights. The front sight has a white dot, and the rear has a white outline. A robust external extractor is fitted into the slide, just aft of the ejection port.

The G29 SF, like its siblings, is all business. In fact, there is nothing pretty at all about the polymer pistol. But in my experience, Glocks usually make up for their lackluster looks with unfailing reliability—a must-have quality in a defensive pistol.

Bear-Busting Power
At first glance, I appreciated my G29’s compact size and expected reliability, but it seemed like a pistol without a purpose. After all, its stubby barrel and fixed sights are hardly ideal for hunting, and based on my experience with my 10mm 1911s, I thought the heavy-recoiling 10mm cartridge would be too much for most shooters to handle from such a compact pistol. However, the promise of bear-stopping power in a lightweight, compact package appealed to me, so I packed up my chronograph and a good supply of 10mm Auto ammunition and headed to the range.

I started with some 7-yard work to see where the sights hit and to get used to the trigger. The G29 hit where I looked and pounded my first few magazines into a nice, fist-sized group. But as I upped the ante with hotter hunting loads, the pistol started to jump around in my hands, opening up my groups. High heat and sweaty hands didn’t help, but subsequent sessions in cooler weather proved that I’m just not man enough to keep the G29 in check if I don’t readjust my grip every few rounds. The recoil isn’t brutal, but it’s certainly noticeable, and the short grip doesn’t provide enough of a purchase for even my small hands. Friends with larger hands had similar problems holding onto the G29 SF.

From the bench, the pistol showed a bit more promise, averaging around 2 inches at 15 yards and producing best groups in the 1.5-inch range with two loads. I also had no trouble ringing MGM’s BC-C Zone target at 100 yards with it. The little pistol displayed impressive accuracy, to be sure, but its fixed sights and short sight radius make it less than ideal for hunting. I also think the short barrel gives up too much velocity to justify the increased recoil.

For example, Double Tap’s 180-grain Nosler JHP averaged 1,162 fps from the 3.7-inch-barreled G29 SF. The same load averages 1,310 from my 5-inch Colt. That 1,162 fps average still beats a 180-grain projectile from the .40 S&W by about 100 fps, but that extra bit of performance comes at a price: 10mm Auto ammo is harder to find, and the Double Tap loads buck around in the hand a lot more than .40 S&W loadings.

It may sound like I’m a bit down on the G29 SF, but the truth is it’s a reliable pistol that shoots great. I would prefer 9mm or .45 ACP for self-defense in urban environments, and I’d opt for its big brother, the G20, for hunting. But the Lilliputian 10mm is ideal for outdoorsmen looking for more power and reach in a concealable package.

Bigger is usually better in bear country. With the right loads, the G29 SF offers that increased power in a package that is small and light enough to carry on extended backcountry excursions. And you can bet that no matter how wet or muddy or dirty it gets, this little big Glock will go bang every time you squeeze the trigger. What’s not to like about that?


The “SF” stands for short frame, and it means the circumference of the grip is reduced by decreasing the length from the backstrap to the trigger.

    Gen 3 Model 20 always felt like a fence post in my hand. Tried the gen 4 and love it. Going to black bear country this fall as my backup.

  • Mazryonh

    Which generation was the Glock 29 you reviewed from?

    “A smaller, bigger hammer” doesn’t make much sense. A better title might have been “a smaller, meaner hammer” which the Glock 29 certainly is compared to a full-size 9mm Parabellum pistol.

    As for getting a better grip on a Glock 29, there are grip extensions mounted on Glock 29 magazines that fit on the bases, which will give your pinky finger more purchase. If you want to use Glock 20 magazines in a 29, there are magazine sleeves for those too that will bridge the gap between the base of the magazine and the bottom of the Glock 29’s grip. There are also the numerous stippling/grip modification services for Glocks that make them thinner or otherwise shorter beyond what you can get from stock models which could help.

    “The promise of bear-stopping power in a lightweight, compact package” has long appealed to those who carry, or end up carrying, snubnose revolvers in magnum cartridges. The Glock 29 has the snubnose .357 magnum revolvers beat in terms of capacity and relative recoil thanks to its magazine capacity and recoil spring assembly, not to mention how full-power 10mm ammunition can come very close to .41 magnum performance levels. I’m sure if you put a miniature red dot sight on your Glock 29 you could use it for short-range hunting.

    • Terry Kremin

      the 10mm can come close to the .41 magnum POLICE LOADS (The cartridge was designed to have two load levels, but use the same brass – so you had .41 Special loads, and then full magnum loads, with the special loads intended for law enforcement), which are no longer offered.

      The regular/standard .41magnum loads you can buy now are the full magnum variety.
      They put out a 210gr bullet at 1200-1350 fps.

      Buffalo Bore 10mm hunting comes close in velocity, but it uses only a 180 gr bullet.

      The 170gr Buffalo Bore .41magnum spits it out at 1650 fps.

      Not very close…

      • Mazryonh

        Have you tried Underwood Ammunition? Before the recent ammo shortage, their website regularly listed ammunition to the tune of 200 gr bullets travelling at 1200+ FPS being available in 10mm. The original Norma loading was specced to this level too.

        Besides, .41 Magnum is a rimmed cartridge, making it largely unsuitable for double-stack or higher magazines. That means you aren’t going to get as much capacity as you can with 10mm Auto.

        • Terry Kremin

          and come with a warning due to its high pressures about feed ramps….

          • Mazryonh

            You use the right tool for the right job. It’s similarly foolish to fire .357 Magnum rounds out of a revolver rated only for .38 Special as it is to use the 10mm rounds I mentioned in a gun without enough chamber support.

            Plenty of aftermarket barrels now with better chamber support for 10mm Glocks now too, and a Glock 20 or 29 can fire .40 S&W or .357 SIG with nothing more than a barrel swap.

  • franco

    The SF really isnt much different than the gen 4. Also, go to BBTI site and see what happens when you compare snub nosed 357,41mag and 44 mag velocity to the 10mm. The Glock is just a light as the alloy framed magnums, half the price, double the capacity and closes the gap on ballistics

  • chazzz

    Since this is a 3rd gen, a stiffer recoil spring woulg help with the fps issue. A 22lb spring will keep the slide/breech closed longer allowing more gas to push the bullet when using close to full power loads. This holds true for the G20 also(which I own). The 4th Gen has a dual spring which probably needs to be stronger also for the stouter loads to get max fps/ftlb,s.. The dual springs in the 4th gen are supposed to make it a lot easier to shoot. Cannot wait to get one, and stiffer spring if needed..

    The author’s “review” was clearly biased and given without having done any pre-research about the product, or the options related to it.
    The FACTS are that a great many people carry a G29 in the field, stoked with 220-230 grain HC lead loads that deliver as much as 700 lb-ft of KE which is very MUCH on par with any “.41 Magnum” top load when fired from a 4″ or less barrel! In fact, the vaunted .44 Magnum, when fired from a 4″ barrel delivers CONSIDERABLY LESS “power” than apparently most out there realize. A 4″ barrel M29 is ballistically very close to a Glock 10mm.
    Then there is the FACT (apparently not known to the author), the for hunting one can easily swap out barrel and magazine to create what is in essence a “G20SF!” This means one can carry the more compact G29 for CCW, and swap in a 4.6″ or longer barrel, plus a 15 to 17 round double-stack magazine for field use – IF DESIRED! Having said that, when stoked with REAL 10mm ammo (which is easily found by any amateur internet search), the G29 delivers ample power to dissuade a large, dangerous predator.
    Then there is the additional FACT that the G29 can be readily loaded with .40 S&W ammo with NO MODIFICATION or barrel swap! This allows the user the added versatility of choosing from a broad selection of .40 S&W, as well as an equally broad selection of 10mm from “mild” (to say the least), to exremely powerful loads that are absolutely the equal or “better” of many other popular revolver cartridges…oh, and it does it in a relatively SMALL package! A 3″ barrel .357 magnum revolver will not weigh less, will not be smaller, will NOT be less bulky, yet WILL be nearly uncontrollable under recoil, while delivering kinetic energies BELOW the 10mm, and doing so with smaller, LIGHTER slugs!
    A .44 Magnum M29 – probably the most compact 6-shot .44 Mag available, when fitted with a short barrel, is HEAVIER, far more bulky, delivers violent recoil, only holds six shots before a MUCH slower reload, and still only delivers about the same kinetic energy as the 10mm! These are all FACTS than anyone NOT biased, and NOT attempting to malign a given pistol or cartridge would RESEARCH if informing and educating the reader were in any way associated with the author’s personal agenda…but the author’s agenda was to denigrate Glock, and denigrate the 10mm, so he of course bothered NOT to pull in all the FACTUAL evidence circulating within millimeters of his fingers (the internet), nor did he do any fact-finding research on his own…he just abused his supposed (according to him) position as one presumed to know something about firearms to MISINFORM the reader…

    The Glock 29 can shoot the 10mm Underwood 200 grain rated at (and CHRONOGRAPHED AT) 1300 fps, or the Underwood 220 grain HC at 1250 fps…yes the 3.7″ barrel will shoot a bit slower than the 4.6″ G20, but not nearly as much as THIS biased “author” would have the reader believe….simply go to and view the actual chronographed results on VIDEO so you can SEE the numbers as they are created!
    The G29 can also shoot the .40 S&W right out of the factory barrel…BECAUSE (and the author clearly does not know any of this), the Glock uses controlled feeding which means the rim slips under the extractor during chambering and thus holds the cartridge against the breech face….shoots the .40 just as well as it does the 10mm!
    The G29 can ALSO be rebarrelled to shoot the 357 Sig, and the 9×25 Dillion. Underwood’s factory loading of the 9×25 kicks over 800 lb-ft of KE from the G20 barrel….certainly it will do less from the G29, but not much less. Plus I must remind the reader that for field use one can easily drop in a 4.7″ or longer barrel which makes the G29 match the G20 step for step!

    Using a conversion barrel the G29 can also shoot the 9×19! FACT…all readily available to anyone wanting to inform the public.

    Overall the G29 is a very versatile pistol that handles full-house 10mm loads with ease….that photo showing the pistol torqued nearly 90 degrees upward was clearly staged, or the “author” is acknowledging to the world that he has weakling wrists, and when he LATER publishes more tripe about G29 malfunctions, his “audience” would do well to go back and see how he limp-wristed the gun in order to induce a stoppage.

    I happen to be a REAL 10mm owner…both G20SF and G29SF and neither torques around like his photo shows when firing REAL 10mm ammo making in excess of 800 lb-ft of KE! I personally chrono’d Underwood 155 grain JHP at 1555 fps (average of 10 shots), for 833 lb-ft KE from a G20SF…a LOT more powerful than the biased author would have you know.

    Additionally, the “proof” as they say in the ACTIONS of all those out in the hunting field who are moving from magnum revolvers to the 10mm for hunting and defense against dangerous animals…that’s not fantasy, it’s FACT, and since gun-buyers tend to be CONSERVATIVE, the surging re-emergence of the 10mm speaks volumes all on its own!

    • Kilibreaux

      And I forgot to mention that .38 Super barrels can be found to fit the G29, but even more importantly, for anyone so inclined, such barrels can be chamber-reamed to accept the nearly identical (dimensionally) 9×23 Winchester which was built to run at 55,000 psi! The 9×23 Win case walls and web area are double the thickness of any other “9mm” type case and makes a GREAT option for someone who wants a genuinely powerful 9mm round but doesn’t quite trust the reliability of a bottleneck design…not to mention the fact that the 357 Sig is pretty lame in factory loads….about on par with lame .38 Super factory loads. Both the Dillion 9×25 and 9×23 Win deliver something actually useful in comparison to the .40 caliber choices.

      Also, for anyone interested, one can fit an aftermarket slide and barrel and start shooting .45ACP/ACP +P/.45 Super/.400 Corbon/.40 Super/, and of course .460 Rowland!

      The Glock “platform” is the ideal foundation for an almost endless variety of caliber/power choices….NONE OF WHICH is true of any revolver.

      And one last point…the .41 Mag “crowd” has been trying to justify their existence for the last 50 years….the police load was ballistically equivalent to a warmish .44 Special, and the “field” version was (just like the .44 Mag) intended to gain maximum performance from 6″ or longer barrels, in rather HUGE revolvers. A “field” power load fired from a M57 4″ will deliver power approximate to the .44 Mag from the same profile….except in .41 it will be a 210 grain slug which is 10 grains LESS than the 10mm 220 grain Underwood, and will measure .410″ versus .400″ (big whuptidoo!), and will deliver approximately the same kinetic energy! Without more BARREL the “old” Magnum cartridges simply cannot deliver maximum performance…but this all gets left out when a biased writer is questing to demean one cartridge over another.

        I am about sick a tired of people comparing 10mm to 41 magnum and 44 magnum. Are you people kidding me with this crap? Is this some sort of inside joke Im not privy to? I think we can all agree that Buffalo Bore stretches the boundaries of what a caliber is capable of so I will use them as my reference for all calibers.

        305 grain item 4A makes 1331ft/s out of a 5.5 inch barrel for 1200 ft/lbs
        340 grain item 4D makes 1401ft/s out of a 5.5 inch barrel for 1482 ft/lbs

        Now, the heavy 44 magnum rounds shortest barrel listed was 5.5 inches so I had to use that, still quite fair since the 10mm rounds are all listed with 5 inch barrels. So what can we conclude from all this information?

        1. NO SIRS, your 10mm is not “basically a 41 or 44 magnum.”

        2. Your 10mm makes ALMOST as much power as a full house 357 magnum, though the 357 has a higher average energy (excluding the snub rounds).

        3. Your probably going to try and argue that there are some loads in 357, 41, and 44 that are weaker than 10mm, yeah… dumbed down low recoil defense loads in the 41 and 44 are about on par with the REAL 10mm. However the REAL 41 magnum and REAL 44 magnum are 1.5 to 2 times as powerful as a full house REAL 10mm.

        So please, stop claiming the 10mm is something it isn’t. It throws down about as much energy as a 357 magnum over a slightly larger surface area. Thats great! Really its awesome! I have own all 3 of the revolvers mentioned and a 10mm Glock 29. Its a great round and I trust it will be as effective as my 357, BUT stop with this hyped up “its a 41 or 44″ BS, its seriously getting OLD!

        • John Pryce

          Speaking as a huge 10mm fan, what you say is valid. That said, try finding a semi-auto in a magnum caliber.
          Magnum calibers are made for revolvers for a reason. 10mm Auto is the .41 magnum of the semi-auto world. In much the same way, .460 Rowland is the .44 of the semi-auto world, and .50AE is the .500S&W.
          With more moving parts, the weapon becomes more fragile. And unless you move into a gas-powered recoil system (DEagle), you have to sacrifice something.

    • Mike

      Go ahead and try shooting the G29 with 40 S&W ammo without changing to a 40 S&W barrel. It will be entertaining to watch. Put it on you tube so we can all get a chuckle out of it.

    If I were running Glock I certainly wouldn’t send you any more “notes” to review my product.
