My 27 with HSTs will outshoot my 23 with GDs out to 20 yards. I don't know why but it's a heck of an accurate gun.Went to WW and went through about 100 rounds today while waiting to pick up the little one from school. I was shooting tighter groups with my G26 than I was with my G17. I guess my brain likes the short barrel. Good thing its my main ccw.
