I have removed the frame and reinserted it into the grip many times, but now I just can't seem to get my P-3AT back together. The hang-up is in the rear and is caused (it seems) by Part # 272 aka Hammer Block. With the frame out, the hammer block is forced to the rear by the hammer block spring and I am unable to seat the frame. I tried to force the hammer block forward with a slim piece of metal as I seated the frame. This worked but the Hammer itself is now locked in the back position and the trigger won't move. Arrggh! Any ideas? Thanks! Also, are the firing pin springs interchangeable between the P-3AT and P-32? I can't tell if I've lost my P-32 firing pin spring or I've got an extra P-3AT firing pin spring (this is possible as I've got lots of extra parts for my P-3AT).
