Acceptable group size for 45 Auto strike fired gun??
When you are loading for 45 Auto, what is an acceptable group size for an XD, Glock, M&P type gun?
Compared to a 1911, I find a striker fired gun to have a lower level of accuracy in my experience. I feel this is due to lower trigger pull quality and poorer barrel fitting.
IMO, fine 1911 or revolver should be around 1" at 15 yards...
My point was simply that a gun with a long mushy ~7lb pull and a barrel fit at one end will not shoot nearly as well as a gun with a SA trigger pull and a fixed or precision fit barrel. . .in my hands, at least.
Therefore, a gu that is capable of 2" 50 yd accuracy will get more extensive load development from me. A 6" 50 yd gun will require less.
That is when I get 1.5" 15yd accuracy I feel like I have got 90+% of what it will do and it is time to go into production!
I've owned several different brands of striker fired .45's, and I've had 1911's that shot great too. However, the Glock 21 and 30 I can shoot just as accurately as any 1911 I've had. Now that doesn't mean it's as easy to shoot accurately as a single action 1911, the Glock trigger does take work to get proficient with, but once you do, it's accurate.
This is from my G21 with KKm barrel although the stock barrel is just as accurate, distance about 15yds, 5rds slow fire, no rest.
