I picked up a new USP-C yesterday and I am noting an issue with the recoil and slide.  If I fire the gun it cycles and fires but the action is pretty weak compared to other GBBs I've had.  When I cycle the slide manually even doing it fast I can feel a little hang up even though the wear markings look pretty good.  The real issue is when I slow cycle the slide.  It completely hangs about an inch from full close.  I have noticed on my two other KWAs that they come close to hanging up but the spring pulls them through, albeit shakily.  I don't expect airsoft guns to be as smooth as their real steel counterparts (Though you guys do a damn good job :)).

So my question is.  Is there a different spring one could recommend to add a bit more oomph but not hamper the backwards cycle?  I know people put 150% 1911 springs on their 226 for example :)

Are you sure the gun is actually cycling fully?

By cycling fully I mean it is recoiling, slapping back the hammer, and properly chambering and firing the next ball.  I haven't had any misfeeds or balls that squirt out the barrel (My NS1 KP45 has really never worked so I am familiar with how bad it could be).  So from a "will it shoot and work" perspective it seems ok...  I'll check out that spring set.  Thanks.
