Bought a basket case FEG HP clone a few weeks back. The previous owner had taken it completely apart and couldnt reassemble it. Upon putting it back together I found that the hammer will fall and catch on the half cock notch when the slide catch is released. Sometimes the safety will engage itself when this happens, sometimes not. The hammer and sear appear to have proper engagement, and have not been modified in any way. I checked all the trigger mechanism, all seems OK there. I did remove the magazine disconnect the last time, but it was doing this before I removed it. Is the trigger bar (vertical piece pivoted off the rear of trigger) supposed to have a slight bend sideways? This one does, and I'm wondering if he bent it, but I dont have one to compare it with.
If you manually pull and release the slide the hammer stays cocked, it only falls when the slide is released using the catch. I suppose it hits harder that way. Any ideas whats going on here?
Thanks
