Here at Glockmeister, we receive many questions about the differences between two of GLOCK's most popular pistols – the Glock 40 MOS and the Glock 20. While both are large-frame 10mm semi-automatic handguns, there are some key differences that might make one model a better fit depending on your needs. In this guide, we compare the Glock 40 and Glock 20’s specs, features and performance to help you decide which GLOCK is right for you.
Introduced in 2019, the Glock 40 MOS is GLOCK’s longest slide pistol built specifically for hunting and long-range handgun shooting. It shares the Glock 20 frame but has a longer slide and barrel for increased velocity and accuracy at extended distances.
Key Glock 40 specs and features:
The grip and controls feel similar to full-size GLOCKs, but updates like the flared magwell enable quick reloads. The precision accuracy from the longer sight radius stands out—enabling hits on distant targets beyond the reach of smaller handguns.
Whether hunting whitetails deep in the backcountry or defending yourself from dangerous predators, the Glock 40 provides powerful precision, with the capability for superb accuracy at 100+ yards that few other factory pistols can match.
The Glock 20 set the standard for full-size 10mm handguns over 25 years ago and remains a versatile powerhouse today. With its standard slide and large frame, the Glock 20 balances serious firepower and carryability.
Key Glock 20 specs and features:
The Glock 20 originated as a hunting and long-range 10mm handgun. But its compact design also suits concealed carry and home defense. With power rivaling the .41 Magnum, the G20 handles medium to large game.
While it may lack the long-distance precision of the G40, the G20 is still remarkably accurate. Its enduring popularity stems from being an extremely versatile handgun.
When evaluating options in the 10mm category, a key deciding factor for many is how comfortable and accurate a given pistol feels on the range. Let's see how the Glock 40 and Glock 20 compare when put to the test.
Specs | Glock 40 MOS | Glock 20 |
---|---|---|
Sight Radius | Excellent – very precise | Good |
Accuracy | Under 2" groups at 50 yards | 2-3" groups at 50 yards |
Recoil Control | Superb – weight perfectly balanced | Moderate – some muzzle flip |
Ergonomics | Large frame suits big hands | Large frame suits big hands |
The Glock 40’s accuracy at range when mounting a red dot sight provides an edge for hunters and competition shooters. But the G20 can certainly still provide power and reasonable control.
While the Glock 40 and Glock 20 share a 10mm chambering, they excel in different applications. The G40 provides specialized long-range precision with optics readiness. The G20 is a generalist offering versatility from self-defense to hunting large game. Carefully weigh your needs to determine if one of these handguns is a better fit.
