I realized something that I should have picked up on sooner. My Glock 27 is the most accurate Glock I own. Though, my new favorite is my 23, and the 22 has a longer sight radius, my 27 smokes them both. I save old targets and take notes and my group size is over a .5 inches tighter on average with the 27. The reason I never noticed it before, (I Guess ), is for some reason I never shot the 27 the same day as the other ones. I guess an old dog can learn new tricks. Does any one else shoot their sub compacts more accurate than their full size? Curious to see if it is just me.
