Finally got back to the range and finished breaking in my K40. This is one sweet shooting gun, just a bit snappy as most 40 s&w guns are. Accuracy and control was excellent, just love that smooth trigger. I had 2 ftf's at about 160 round count, at which point the gun was kind of dirty. The S&B ammo wasn't the cleanest I've shot. The next 50 rounds of American Eagle ran flawless. Towards the end of shooting 200 rounds I could feel the guns action smoothing out. I also had the front sight replaced with a Meprolight tritium night sight, that I got from Kahr's website, as I will carry this gun from time to time.
