So I just bought a used p45. Only have about 150 rounds through it myself but I havent had any problems. The gun seems pretty well broke in. I was on the Kahr website and I noticed that my gun has the "old" slide style. They only mention the dovetails being cut differently but I am wondering if they changed anything else. Im just looking for a potential problem before it becomes trouble.. I was impressed by its natural aim and minimal recoil for a gun of its size.The sights hit way low but it seems to be a good point and shoot gun though. This gun was intended for primary ccw but my new Glock 27 holster is feeling so good right now this Kahr may wind up in the safe for now.
