PMI guns all work the same
first thing to check is the hammer o-ring. make sure it's in good shape and lubed. (also check the bolt o-rings while things are apart)
if you've had a gun for awhile, the sear may be wearing down. check to see if it's rounded off or if the edges are still well defined and sharp.. also check the Hammer where the sear makes contact with it incase there's a lot of wear there.
what velocity are you shooting at?
