Granted, I'm new to the 38, but took both the 17 and 38 to the range today and shot 'em side by side. Not a lot of noticeable difference TO ME, but then I'm not particularly sensitive to recoil. The 38 might have had a slightly stronger "buck" when I pulled the trigger. Was shooting WWB in the 17, and it felt pretty mild. The 38 held mostly my weak reloads, one so weak it failed to extract even. And it seemed pretty mild as well. I paced off about 12 yards and set up these two side by side 8" circles. The difference in accuracy could have something to do with shooting 3 different batches of .45 GAP ammo, or it might have been due to my newness with the pistol and anticipating stronger recoil. Anyway, I am also anticipating becoming more accurate with my new 45GAP and in building more consistent loads. More to follow.... Wanna kill these ads? We can help!
