Which screw is this? I had a C3 model and didn't see a screw. I'd like to see pics if you have it though.
On a related note, my Taurus PT-1911's firing pin safety recently gave me trouble. Every so often it wouldn't fire (dry firing). I couldn't pull the trigger. I took it apart and thought it was the disconnector. It was actually the "barbell" that is the firing pin block getting stuck in the up position. Granted, the spring behind it was a replacement one that I cut to size. I guess it was too short. Still trying to figure out how this is connected to me not being able to pull the trigger, but it solved the problem when I took the FPS out. Need to order a new one.
