In my opinion the Glock 29 in 10mm is the most versatile semi-automatic handgun made. I also feel the 10mm is the most versatile semi-auto cartridge ever made. This combination offers an unbeatable package of configuration and use for the owner. Below I will summarize why and how I have come to this opinion and open your eyes not only to a great cartridge, but a great handgun that I feel everyone should have in their collection.

The 10mm Cartridge

First I want to discuss the 10mm cartridge itself. before I get into the handgun. Most will say that the 10mm cartridge was developed in 1983 by Colonel Jeff Cooper. While that is true, I want to give credit to Whit Collins, Irv Stone, and John French along with Colonel Cooper for actually beginning the research that led to the development of the .40 G&A in 1972 which led to the development of both the 40 S&W and 10mm cartridges.

The 10mm cartridge lost popularity in 1990 when the shorter cartridge 40 S&W was introduced. A lot of manufacturers stopped making handguns chambered in 10mm and started to offer handguns chambered in 40 S&W and it faded into the sunset, so to say.

One manufacturer that did offer a 10mm handgun starting in 1991 was Glock with the model 20. The Glock 29 was then introduced in 1997. In 2009 Glock offered the 29SF model and I decided to purchase it. For years mostly watered down factory loads were offered that did not exploit the potential of the 10mm cartridge which forced die hard 10mm fans to resort to reloading their own. Recently however, the 10mm cartridge has had a resurgence and more manufacturers are starting to offer full power loads for it such as Buffalo Bore, DoubleTap, and Underwood.

In below discussion of the 10mm cartridge, unless noted, I will refer to actual velocities out of a Glock 29 3.77″ barrel that were recorded by myself and or others.

The 10mm cartridge is very versatile in it’s offerings:

If you want a heavy high energy round, Buffalo Bore offers a 180gr JHP that moves at 1270fps and produces 645ft lbs of energy.

Underwood offers a 135 grain JHP load that moves at 1500fps @ 675 ft lbs of energy if you want a light and fast round with lots of energy.

Buffalo Bore offers a hard cast lead 220 grain round that moves at 1050 fps with 533 ft lbs of energy and DoubleTap offers a 200 gr FMJ load that moves at 1150fps and produces 587 ft lbs of energy If you a want heavy load with lots of penetration.

PMC offers a reduced power180gr JHP that moves at around 950 fps and produces 360 ft. lbs of energy if you want heavy load but one that has low recoil.

If you are looking good mid-weight load that performs , Underwood offers a 165gr JHP that moves at 1310 fps and produces 629 ft lbs of energy.

Other great performers are:

DoubleTap 135gr JHP 1390fps/570ft lbs

DoubleTap 165gr JHP 1300fps/619 ft lbs

DoubleTap 155gr JHP 1300fps/582 ft lbs

Underwood 180gr JHP 1230fps/605 ft lbs

All these bullets offer great sectional density with incredible energy delivered to the target at high velocity. A good reference is this 10MM Chart offered online by drsjr1969. It has his real life chronograph results out of his 10mm handguns.

There are quite a few internet myths regarding the 10mm Auto cartridge and I want to dispel them right now.

First, that it is too expensive. This is incorrect. Not only are self-defense rounds the same as .45ACP offerings, but it can be reloaded for the same or cheaper than other calibers.

Second is that it is too large and requires a large firearm. This is also incorrect. The cartridge fits in the same frame size as most 45 ACP offerings and is slightly larger than the .40 S&W or 9mm frames.

Third, is that it has too much recoil. Incorrect, it recoils the same or less that .45 ACP and in the Glock design, recoil is not bad at all as you will see from my videos.

Cartridge performance and over penetration is another myth. A thread Professional Soldiers offers the following gel test data done by Double Tap. This data was e-mailed out to people and I cannot find the original source at this time, however it has been cross-posted on many forums and was provided by the owner of DoubleTap (I am not sure what handgun was used) :

All of these tests were done using 10% ballistic gelatin provided by Vyse gelatin using all FBI protocols and 4 layers of denim and two layers of light cotton T-shirt in front of the gelatin.

125gr Gold DOt JHP @ 1725fps – 15.0″ / .74″

As you can see, not only does the 10mm offering expand well, it penetrated no further than the .45ACP. Another internet myth dispelled.

As far as trajectory, the 10mm is a very flat shooting cartridge. These charts were provided courtesy of sqlbullet from the AR-15 Armory Forum. As you can see, the 10mm is very flat shooting out to 100 yards with a 100 yard zero, which is what I would consider the maximum range for handgun hunting.

25 Yard Zero:

50 Yard Zero:

100 Yard Zero:

It is for these reasons I feel the 10mm is the most versatile semi-auto handgun cartridge available today. It is often overlooked and dismissed by many. It’s range of light to heavy bullets, flat trajectory, and excellent sectional density offers the user a variety of loads to choose from for any application whether that be hunting, self-defense, competition, or target shooting.

The Glock 29 semi-automatic handgun offers it’s owner many different options and configurations:

For concealed carry configuration the factory 10 round magazines with or without the finger extensions offer a 10+1 concealable package. You can carry a 15 round Glock 20 magazine for a reload and have 26 rounds at your disposal. It conceals well in a Dale Fricke Archangel Holster, even with the 15 round magazines.

It can be uploaded to a 15+1 round configuration with or without sleeves which are readily available online at vendors such as GlockStore and are not expensive.

For owners that want even more capacity, Arredondo offers a 20 round upgrade which I own and have tested with favorable and reliable results. These can also be carried as a spare, but take up more real estate than the 15 round Glock 20 magazines. I found they are good for when I am in the back country and I am not worried about concealing the handgun.

The Glock 29 can also easily change over to .357 Sig, 40 S&W, or 9X25 with a simple barrel replacement. Barrels run around $115-$160 each and are offered by manufacturers such as Storm Lake and Lone Wolf.

The handgun itself:

GRIP: The grip is smaller than a standard G30\G29 grip. It feels more like a G17/19/27 and you don’t have to stretch out to reach the trigger. The grip is comfortable and easy to get your hand around and hold. More so with the grip extender on the 10 round mags. It just fits. So unless you have huge hands I recommend the SF. I at least recommend you hold both of them before you buy to see what fits best.

SIGHTS: Standard stock Glock three dot plastic sights. High visibility and easy to acquire. The only thing I would change to a more durable steel version.

RECOIL: Recoil? What recoil? Every shot I took in these videos was one-handed and rapid fire as fast as I was comfortable . I was pleasantly surprised how the firearm handles the recoil. The Buffalo Bore 180gr JHP had a little more snap to it but it felt no more than a standard .45 and as you will see below my follow-up shots were excellent and it patterned great for one-handed on the move.

TRIGGER: Measured out at 77oz on the standard scale or approx 4.8lbs from center. It is a typical Glock trigger. You either hate it or you do not. The reset is nice and it is not mushy and it is a crisp reset click that is easy to feel and makes managing the trigger on followup shots easy. As I fired it the trigger components polished up with wear and brought it to around 4.5lbs. Typical Glock trigger. Once you get used to it, you can work it with ease.

WEIGHT/SIZE: Lightweight, the little extra width is barely noticeable and the shorter back-strap on the SF is a definite benefit. It conceals well but unlike slim handguns does have some bulk to it. It is the same size as the Glock 30 in 45 ACP.

In conclusion, anyone looking for a multifaceted handgun that can be configured for concealed carry, recreational shooting, competition, or hunting should seriously consider the versatility of the Glock 29.

With four caliber choices offered with a simple barrel change: 10mm, .357 Sig, 40 S&W and 9×25 Dillon and multiple capacity configurations of 10/15/20 (10mm).

It is a semi-automatic handgun that fires a high performance cartridge that never really got popular up against the 9mm, 45ACP, and 40 S&W due to it’s lack popularity among law enforcement. If you do not own a Glock 29 or 10mm handgun you really just don’t know what you are missing.
