Thanks for the barrel advice, that should clear things up. As for grinding my hammer, yeah that was stupid but it's too late now. The reason I suspected the hammer is because there is a slight amount of play to the hammer after it is cocked. You can pull it back a tad further, preventing any contact with the blowback mechanism. When I held it down like this it seemed to work fine.

Does anyone know if the USP Compact hammer is interchangeable with the USP .45 full size? Or, does anyone know the KSC part number for the hammer (I seem to have misplaced my manual)?

Thanks,

Alex
