I have never claimed to be a great shot but Glocks have a way of bringing out the best in me... I have heard over and over that Glocks especially in the larger calibers are not "tack drivers" but are just good defensive pistols. I wish I had a picture of the 25 yard group a friend of mine got with his Glock 29 10mm. It was unreal! 10 shots so tight you could cover them with a Silver Dollar. Here is a group I shot a while back with my 21 at between 45 and 50 feet. Please post some of your bigger bore Glock pic groups.
