Gen 4 Glock 20 Review With Video

[plouffedaddy]

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

Heres a video I did to show the firearm in action. I do some shooting, demonstrate the ejection pattern with hot ammo, a 15m group, table top review (with part numbers), and some chronograph testing.

Nice work.
Did you get 'em from Ed's.
I thought about the Gen 4 20 to complement my G29, but got the Gen3 last week instead because it fits my hand better.

I did pick it up from Eds.

The beauty of having the Gen3, SF, and Gen4 model out now is that everyone can pick which they like best. I'm sure the Gen3 is a beast too--and the option of adding a heavier recoil spring helps too...

Don't worry about it. I have a gen4 19 with a few thousand rounds through it that just won't develop wear marks. The only way you can tell I actually shoot it is some finish wear on the extractor and barrel hood. I like them once they develop a little "character," but this one isn't developing it very fast.

Oh I'm not worried about it but I just love that old shiny Glock finish. It was freakishly durable. That said, I own several newer Glocks with various finishes and they're all good finishes for sure.

Is the Gen 4 with the SF sized frame or the standard sized frame?

 

[plouffedaddy]

It has the SF size frame without backstraps, regular Gen3 frame with the medium backstrap.
