All other things being equal, how accurate are they compared to a Beretta Model 92?
slide to barrel lockup would be more significant to accuracy than what is going on after the bullet leaves the barrel
The Glocks are plenty accurate, but the Beretta 92 points much better.
For me, that just means that my Glocks require more practice, and my 92 makes me look like a pro at the range. My 92 has always been a great shooter.
My Glocks (a 21 and 19) as well as my Beretta 92 have never given me a single problem, and I wouldn't part with any of them. My G19 is my primary weapon, FWIW.
