I don't know much about them myself... I THINK the USPc has some type of it, but not exactly the same, the HK45 has I believe the same as the USPc as well... again, I don't know for sure, just going by what i've read about them all.
this is my USP 45 compact if you notice on the recoil rod and spring there is a white Plastic Piece I think it is to stop the slide and not allow it to compress the spring all the way back
