If you’ve spent any time around the counter at a gun shop lately, you’ve probably noticed the Glock 10mm lineup is having a moment. The 10mm Auto never really went away, but between bear country hikers, hog hunters, and shooters who want more authority than a 9mm without stepping up to a full-on hand cannon, the cartridge is back in a big way. And when people start asking which Glock 10mm pistol they should buy, the conversation almost always lands on three models.
Glock currently makes three pistols chambered in 10mm Auto: the Glock 20, the Glock 29, and the Glock 40 MOS. They all run the same cartridge, but they’re built for genuinely different jobs. Picking the wrong one isn’t the end of the world, but it does mean you might end up with a hunting gun you can’t comfortably carry, or a carry gun that beats up your hand every time you touch off a hot hunting load. We put the three leading Glock 10mm models head-to-head so you can figure out which one actually fits how you plan to use it.
Why the 10mm Auto Still Earns Its Reputation
The Glock 10mm was born out of the FBI’s search for a cartridge with more stopping power after the 1986 Miami shootout, and even though the Bureau eventually moved on to lighter rounds, the Glock 10mm never lost its following among hunters and backcountry travelers. It bridges the gap between a service pistol caliber and a .41 Magnum revolver load. A Glock 10mm can be loaded soft for practice and defense, or pushed hot enough with a 200-grain hard-cast bullet to be a legitimate option for deterring a charging black bear or hunting deer-sized game at modest distances.
That flexibility is exactly why Glock builds three different platforms for it instead of just one.
The Lineup: Three Glock 10mm Pistols, Three Different Jobs
Glock 20, The All-Rounder
The Glock 20 is the original 10mm Glock and still the one most people land on. It’s a full-size, double-stack pistol with a 4.61-inch barrel and an overall length right around 8.07 inches, holding 15+1 rounds of 10mm. It’s big enough to manage recoil well and shoot accurately at distance, but compact enough to still work for open carry, truck gun duty, or a duty holster.
What stands out about the G20 is how balanced it is. It’s not the easiest gun to conceal, but it’s not trying to be. It’s the pistol that does everything reasonably well, which is exactly why it’s the best-selling 10mm Glock on the market.
Best for: hikers and backcountry travelers who want serious bear-defense capability, range shooters who want full-power 10mm without subcompact recoil, and anyone who wants one 10mm pistol that covers most situations.
Glock 29, The Subcompact Carry Option
The Glock 29 takes the same 10mm cartridge and stuffs it into a subcompact frame, with a 3.78-inch barrel and an overall length under 7 inches. Standard capacity is 10+1, with 15-round magazines available as an upgrade. It’s noticeably smaller and lighter than the G20, which makes it far more practical to actually carry on your hip every day.
The trade-off is recoil. Less mass and a shorter slide mean more felt recoil and more muzzle flip than the G20, especially with hotter hunting-style loads. Most owners run lighter-recoiling defensive ammunition in the G29 and save the heavy stuff for the bigger guns in the lineup.
Best for: everyday carry or backcountry sidearm duty where size and weight matter more than minimizing recoil, and shooters who already own a 10mm carbine or larger 10mm pistol and want magazine compatibility.
Glock 40 MOS, The Long-Range Hunting Pistol
The Glock 40 MOS is the outlier of the group, built specifically for hunters and long-range handgun shooters rather than carry or duty use. It shares the G20’s frame but adds a 6.02-inch barrel and a noticeably longer slide, which translates into a longer sight radius, higher velocity, and better accuracy at extended distances. The factory Modular Optic System (MOS) cut makes mounting a red dot straightforward, which matters a lot when you’re trying to make a confident shot on game at 40, 50, or even 75 yards.
It’s the largest and heaviest of the three, and it’s not a gun most people are going to carry concealed. It’s purpose-built, and it does that one purpose better than the other two.
Best for: hunters who want a dedicated 10mm hunting handgun, shooters who plan to run a red dot, and anyone prioritizing accuracy and velocity over portability.
Side-by-Side Comparison
| Glock 20 | Glock 29 | Glock 40 MOS | |
|---|---|---|---|
| Barrel Length | 4.61 in | 3.78 in | 6.02 in |
| Overall Length | ~8.07 in | ~6.97 in | ~9.5 in |
| Standard Capacity | 15+1 | 10+1 (15+1 available) | 15+1 |
| Optic Ready | No (standard models) | No (standard models) | Yes (MOS) |
| Felt Recoil | Moderate | Highest of the three | Lowest of the three |
| Primary Role | All-around / bear defense | Concealed carry / EDC | Hunting / long-range |
If you’re shopping Gen5 options, you’ll also pick up small but useful upgrades across the lineup, including the Glock Marksman Barrel for better accuracy, no finger grooves on the frame for a more universal grip, an ambidextrous slide stop, and a flared magwell for faster reloads.
So Which One Should You Actually Buy?
Honestly, it comes down to what you’re solving for. If you want one pistol that handles bear country, the range, and the occasional open-carry trip without much compromise, the Glock 20 is the easiest recommendation. If concealment and daily carry weight matter more to you than minimizing recoil, the Glock 29 is the only one of the three that’s realistically going to ride comfortably inside the waistband. And if you’re a hunter who wants to put a red dot on a 10mm and stretch your effective range, the Glock 40 MOS is built for exactly that job and nothing else.
A lot of serious 10mm shooters actually end up owning two of the three a G20 or G29 for carry, paired with a G40 MOS for hunting season since magazines and manual of arms carry over between all three platforms.

Don’t Forget the Ammo
A 10mm pistol is only as good as what you’re feeding it, and this cartridge has more range in bullet weight and velocity than almost any other semi-auto handgun round on the market. For practice, a 180-grain FMJ load keeps cost reasonable and recoil manageable. For backcountry defense against bears or large predators, look for a 200-grain hard-cast or bonded bullet built for deep penetration. For everyday defensive carry in something like a Glock 29, a faster-expanding 135 to 165-grain hollow point will be more controllable shot to shot.

Frequently Asked Questions
Is 10mm Auto good for self-defense?
Yes, with the right ammunition. A 10mm loaded with a defensive hollow point at moderate velocity performs comparably to other major defensive calibers, while still giving you the option to load up to magnum-level power for backcountry use.
Which Glock 10mm is best for bear defense?
Most backcountry guides and hunters lean toward the Glock 20 for bear defense, since it balances capacity, manageable recoil, and the ability to run heavy hard-cast loads effectively. The Glock 40 MOS is also a strong choice if you’re willing to carry the extra size and want the option of a red dot.
Can I shoot .40 S&W ammunition in a Glock 10mm pistol?
No. Despite the similar bullet diameter, 10mm Auto and .40 S&W are different cartridges with different case dimensions and pressures. Never fire .40 S&W ammunition in a 10mm chamber or vice versa.
Are Gen5 Glock 10mm pistols worth the upgrade over Gen4?
If you’re buying new, the Gen5 updates, including the improved barrel rifling and ambidextrous controls, are worth having. If you already own a reliable Gen4 model, there’s no functional reason to upgrade just for the sake of it.
Final Thoughts
There isn’t a single “best” Glock 10mm, just the one that’s best for what you’re actually going to do with it. The team at Golden Brothers Co has been helping South Georgia shooters and hunters make this exact call for well over a century, and we’re happy to talk through the trade-offs in person or over the phone before you commit to one.
