Glock 20 or Glock 40 M.O.S.: Which 10mm is Right for You?
There is no denying the popularity of Glock 9mm pistols. Capacity, low recoil, dependability, and affordable ammo are all advantages that make models like the Glock 19 the gold standard for concealed carry and high-volume shooting.
Although these models will serve most competitive and defensive shooters very capably, there are some situations and defensive applications that demand the most firepower available in a reliable semi-automatic pistol. That’s where the Glock 10mm comes in. There is a lot of debate on the Glock 20 vs Glock 40, so we thought we would give you the low down on both to help you know which you might want to pick up for the range. So, Glock 20 or Glock 40 10mm? You can decide for yourself after reading this post.
Glock 20 Gen4 Overview
The Glock 20 Gen4 has become one the top handgun choices for backcountry bow hunters, professional guides in Alaska, and anyone else requiring a hard-hitting pistol for predator defense. With a 4.6” barrel, the Glock 20 Gen4 can launch a 200-grain bullet at approximately 1,300 fps and a lighter 135-grain projectile at an impressive 1,600 fps. The real game changer is the 15-round capacity and controllability of the Glock 20.
Compared to something like a .44 Mag revolver, the Glock is faster out of the holster, and follow-up shots are easier to fire quickly and accurately. The 10mm ammo also has less recoil than the .44 Mag. Some will praise the .44 Mag and argue the benefits of the more powerful Magnum cartridge. We get it. The .44 is and always has been an excellent round and is a great option for bear defense.
Where the Glock 10mm pulls ahead for a lot of outdoorsmen is the lighter weight of the pistol compared to a big bore revolver. If you’re backpacking into the backcountry, weight is very important. With the revolver you have 5 or 6 shots and then it’s time to reload– under pressure, as fast as possible. With the Glock 20 you have 15 shots, insert the next mag, then you have 15 more. We have found the Glock 20 in 10mm Auto to be the best compromise of weight, power, capacity, and manageable recoil for many customers and we cannot recommend it enough!
Glock 20 Gen4 Specs
The 10mm Glock 20 provides nothing short of the firepower you need for protection on every hunt. The use of Glock hi-tech polymer considerably reduces felt recoil. The modular backstrap design lets the user adapt the grip to hand size, and the frame surface exhibits the scientifically-designed Gen4 rough textured technology. The Glock 20 Gen 4 frame also retains the Glock accessory rail for accessory attachment.

Glock 40 Gen4 MOS Overview
The Glock 40 Gen4 M.O.S. has all the same benefits as the Glock 20 but includes a couple key features that make it more suited to those who plan on hunting with it. The barrel on this Glock 40 is lengthened to 6.02” which provides increased velocity and more kinetic energy. The longer sight radius can help with lining up those longer shots if you are using iron sights exclusively. The Glock 40 MOS also includes the Modular Optic System, which allows you to easily mount an optic to the slide.
There are several advantages to mounting a red dot sight on your Glock 40 for hunting. One of these is that it provides low-light visibility. Even though your iron sights are hard to see in failing light or your vision may not be what it used to be, you can easily see the red dot of your optic and adjust the brightness as needed. Another major advantage is being able to stay “target focused” with a red dot. When using iron sights, you have to line up your sights and then shift your hard focus from the target to your front sight and then break the shot, which takes time. However, a red dot allows you to just put the red dot on the target and then pull the trigger.
Whether you choose to add an optic to your Glock 40 Gen4 MOS or you choose to hunt with the pistol sights, you will have the added velocity provided by the longer barrel. For hunting, this really is the ultimate Glock 10mm!
Glock 40 Gen4 Specs
The Glock 40 MOS combines a longer slide and barrel to deliver improved velocity with a high magazine capacity. It features the Glock Safe Action system which provides a consistent trigger pull from the first to the last round. The three automatic independently operating mechanical safeties are built into the fire control system of the pistol. All three safeties disengage sequentially as the trigger is pulled and automatically re-engaged when the trigger is released, making the Glock a safe choice that can also be deployed quickly.
