Hello! I have a pre-B 75. I just bought it used, and haven't even shot it yet. After getting the pistol, I noticed that the hammer would drop with the slide when I was racking the slide. It does this 5 out of 10 times. Also, once in awhile, I can push on the hammer and it will drop without touching the trigger. Double action seems to work fine. I'm using an old ear plug to protect the firing pin during dry firing to protect the pistol. Any thoughts on this issue? It really doesn't look like it's been fired much at all. I called CGW, and they recommended I replace hammer, sear spring, and install adjustable sear. Almost $150 worth of parts, on a gun I already have $350 into. Kinda hard to take, for a cheap skate like me!
