How far from your point of aim are you guys willing to let your shots stray and stillo be comfortabble using the gun for concealed carry. Also, at what distance do you test fire such guns? My Kahr P45 is still (after having the barrel swapped out by Kahr) shooting 2-3 inches low and a little to the left at 7-1/2 yards. Should I just get rid of it? I like the size and firepower though. Advice welcomed. Thanks.
