How good is the accuracy on the Glock 20 10mm ?


February 15, 2012, 07:00 PM
Thinking about ordering a Glock 20 SF (short frame) this week and just wondered how good the accuracy was with this gun? The model 20 has the 4.6" barrel. Also how's the recoil. I plan on shooting some double tap ammo out of it. The 135 grain nosler jhp at 1600 fps.

The gun is very accurate if you can do your part. Have you had any experience with the 10mm round? Or any other high(er) caliber pistols?

Recoil won't be weak, but it won't be bad either. Just enough to be a fun challenge. That's a big round gun. Easy to grip. I prefer the regular frame.

You'll need decent sights to improve accuracy to the point we can even talk about it. Glocks are just about as accurate as anything out there short of a custom 1911. But stock thick plastic sights are limiting to my eyes.

I like the Warren Sevigny comp rear, and a .110 wide Dawson front fibre optic.

There's no doubt I would put on top notch sights and probably a bar-sto or lone wolf match barrel. Yes i have experience with 10mm's, .357's, .44 mags, .40 s&w's, 9mm's, and I currently carry a .45 acp. I'm just real curious how accurate that factory Glock barrel would be. I can definitely do my part.

I agree with zerodefect as far as the sights go. On my Glock 19, and the other Glocks that I have shot (G20 included) the sights were the main limiting factor (the other being my hands are a little too small for the G20). I am fine with them for a defensive role, but they do not do the accuracy that the weapon is capable of justice, if you know what I mean.

Even with the hottest Double Tap 200 gr loads recoil is much softer than any 357 mag revolver with hot loads in it. The wide grip along with Glocks grip angle really soak up recoil.

Mine has Glock factory night sights. I have no trouble keeping all shots inside the head on a human silouette target at 50 yards. At 10-12 yards I can empty a magazine fairly rapidly and leave one hole about 2" in diameter in the target

With a good well fitted aftermarket barrel, I found the G20 to be quite accurate. The weak link was the poor factory sights on mine after I fixed the barrel.

As others have stated, they are pretty darned accurate. Recoil is a tad more than the average .40S&W (which kind of figures since the two rounds are so similar). The DT 135's are pretty mild in the recoil department.

I have compared my G20SF with a S&W M&P40 and found that with loads of similar power, the G20 feels softer shooting and more controllable. You have to load the G20 with some pretty hot loads to get the same felt recoil and snap as you get with garden variety .40 Short and Weak from the M&P.

BTW, dont expect to get a legit 1600ft/s from those DT 135's, they will be closer to 1450ish. Of course, if you swap out the stock barrel for a 6in Lone Wolf barrel you will get a lot closer to the advertised velocity.

This guy does some great videos where he chronographs a bunch of different 10mm ammo.

These are a couple of groups that my cousin shot with his G20. I have seen very similar groups with my G20SF.

Ask the Nuge his daughter shoots bowling pins at 100 yards with one.

There is a video of a guy on YouTube shooting at a steel plate at 200+ yards with a glock 40 (wth cheap ammo) He was hitting it 30% of the time. The gun is more accurate then the shooter.

the stock g20 is fine and very accurate.

i replaced the stock 17lbs spring with a 21lbs and a stainless guiderod.
best thing i ever did. still cycles 100percent with all ammo but a lot softer shooting and the brass stays a lot closer.

if u get a g20 or 29, u wont be dissappointed.

Mine can't compete with my Witness Limited 10 or Kimber Stainless Target, but it's just as accurate as any other combat auto. I shoot my S&W 1006 a bit better, but I expect mechanical accuracy of the Glock is similar.

BTW, 10mm is an addiction for which there is no cure :D

Life is good with a G20.

I found recoil on the #20 to be similar to the #21; it just happens a little faster.

Haven't had too much experience with the 20 (my buddy has one), but I am pretty good with the thing. Like all Glocks (and modern pistols, for that matter), it'll be more accurate than you.

At any respectable pistol range and a bit beyond, the Glock 20 is fairly accurate. I have the standard frame and not the SF. I do not have very large hands and I have full coverage on the grip and the trigger is not a stretch. I think some people with smaller hands may be challenged.

The stock sights work well for daytime shooting, however, I will want night sights before I would feel very comfortable at night.

One great feature of the Glock 20 is that by simply changing the barrel with a conversion barrel, it handles 10mm, 40S&W, 357 SIG and 9x25. The 40S&W and 357 SIG does not require a magazine change. I do not know about the 9x25.

Recoil is not bad, but I have been firing hot loads for over 30 years. It's not like firing hot loads in a scandium J-frame.

The Glock 20 really endears itself once you have it by your side. I have not had problems finding ammo, but I have not tried to get ammo for it on the road.

Go with a G21 on a budget, and get a conversion barrel to enjoy both worlds.
