I know there have been a lot of talk about 10mm's and the Glock 20, etc...(I even started a couple)...

But, what can I honestly expect for accuracy out of one of them. That is important to me because it will be a range gun and carried to the field (hunting-try to take a varmint every now and then for some fun with it!). I was at a gun shop and the person behind the counter was telling me how it was one of the most accurate Glock models made. I am assuming that is because of the 10mm round itself???
I am hoping it would give me better than combat accuracy...like around 2" or so at 25/30 yards...or is this only capable with an aftermarket barrel...or not at all?

Also...I am thinking if I get one, about putting a red-dot scope on it. Has anyone done this with good success? What is a good mount and optics for this?

It won't be my self defense gun...(although it probably should be with that round...:eek: )...or maybe it would become one if I could use the red dot scope quickly with the 20.

Thanks for the help!

If you are able to shoot 2'' at 25 yards, the Glock 20 should do that. I would not count on anything better though. As far as red dots I have never seen one on a Glock, not saying it is not possible, just never seen one. I would think you might be better off getting a laser sight. By the way I love my Glock 20.

I've owned quite a few Glocks in my heyday of shooting.
The 20 was noticably more accurate than any other Glock.
I did not get the most out of it untill I put Heinie sights on it. During my best summer of shooting, I had quite a few offhand groups of 2.5" or less at 25 yards. I even got that level of accuracy with a KKM .40 drop in barrel in the 20.
There are very few pistols that have bested the 20 in my hands, the S&W 952-2, a Freedom Arms 97/.357 and the H&K USP 9mm Elite are the only ones that outshot it.
The trouble with red dot scopes and Glocks is the slop between the frame and slide. A frame mounted dot sight may be less accurate than good open sights. The other alternative is a red dot that rides on the slide like the Docter or JP sights that mount on the rear sight slot, ot the C-More 'slide ride' sight that would require tapping two holes on the top of the slide.
I would say either the fixed Heinie slantpro sights or the Dawson Precision adjustables are the way to go.

If you go to WWW.Topglock.com they have every thing you wanted. Red Dot sights; mount; etc.

The 10mm glocks are unique among 10mms in that they were designed for the 10mm and later applied to things like .45 ACP, .357SIG etc
So not only is it one of the flattest trajectory pistol rounds (very accurate) but the frame was specificly made for it, just like the Glock 17 frame was designed for the 9mm. All the other glock models are adapted to fire rounds they were not designed specificly for.

Also compare that to most other 10mm guns on the market that were modified from .45 guns to shoot 10mm.
So yes the glock 20, the 17 and the compact versions of both are the nicest models Glock makes as they were the only ones designed from scratch specificly to operate around the round that they fire.

I have shot a glock 20 and it was very accurate but I have heard the 357sig is more accurate. I have a glock 33 and it is very accurate for such a small barrel.

I have a G19,22,31,and 20. The 10mm is the most accurate of them all. The 9mm has been the least accurate. Ive seen some good groups with the 45s too. 2in at 25 open sights is possible but wouldnt be average offhand. Never used a red dot so i dont know how much it helps.
