KWA USP hammer not always staying back

I got a used USP on the boards quite some time ago at this point. Right out of the box the trigger snapped which was quite a feat for me to replace. Literally 1 mag after getting the gun back together the slide catch snapped. I've yet to replace that but it's trivial.

Anyway since day one I've had issues with the hammer not always staying back when manually cocked. I've yet to actually take it to a game so I haven't put many rounds through it. The few times I've plinked the hammer seems to stay back when cycling with gas and BBs. when I pull the slide back it also seems to be hit and miss. It also seems that if the hammer is locked back and I pull it back a bit further sometimes it will release.

When I was doing the trigger replace I took a look at all the parts to see if anything had obvious wear that could cause it not to catch all the time. I couldn't find anything obvious but I also really don't know what I'm doing.

Any ideas?
