Gen4 Glock 20 HD Review: The 10mm G20 Delivers

Many devout fans of the 10mm love their Glock 20, myself included. So when I heard the Generation 4 version was released, I jumped at the chance to pick one up. I really like the Gen 4 grip on my other Glocks and I thought it would be especially helpful with the recoil of some hot 10mm rounds. Turns out I was right.

I ordered the gun the day it came out and had it in my paws the next day. I cleaned it, lubricated it to specs, turned the rear sight around (I don't like the Glock sight picture), and patiently waited for the weekend to put some rounds through the beast.

Pros:
-Glock grip angle helps absorb the 10mm recoil (one man's opinion)
-Cost: many other 10mm pistols sell for double what the G20 sells for
-Accuracy: the gun is more accurate than I am
-Positive ejection with both hot and weak loads
-Easy to maintain
-Gen 4 grip surface helps keep a firm grip on the gun, even when your hands are sweating
-Low bore axis helps tame the recoil
-Lots of aftermarket support (holsters, sights, ect....)
-100% reliable so far

Cons:
-new to the market so heavy recoil springs aren't yet available
-the finish isn't the old glossy Glock finish of a few years ago so finish durability is unknown

Nice vid and great recoil control. I have a G20 Gen 4 FDE and it's the only other one I have seen. I was thinking of making a review like this just to show others it's out there but without the range part. Worth it?

[Mrgunsngear]

It certainly isn't going to hurt. I figure the more information out there the better.

I've never fired a 10mm before,,how is the recoil,or kick or muzzle flip compared to a 45 ACP?

[Mrgunsngear]

With full power loads it's a good bit more than 45ACP.

Great video, man. I love the Gen 4 20. I still prefer the Gen 3 in the 9mm Glocks, but in my experience the Gen 4 recoil assembly fairs better with hotter defensive 10mm loads. Haven't had trouble with my 10-40 barrel either. Glock definitely saved this badass round from obscurity, imo.

[Mrgunsngear]

Agreed.

[fffourtwenty]

Ok, will do. I have a G17 Gen3, G17 Gen3 20th Anniversary and a G17 Gen4 OD to review also

[Mrgunsngear]

Thanks.

Love the 10mm! Nice review
