The SR9c doesn't take clips. It uses magazines. I'm not trying to be a terminology elitist...just trying to keep you from getting recognized as an easy "mark" some place and getting taken advantage of.
Anyway, you may also be limp-wristing. Shorter barrel and lower weight theoretically give the gun a snappier recoil, and if you don't have a solid grip, the gun won't cycle properly.
Take it out to the range w/ a friend and after you suffer your failures, have your buddy shoot it and see if it happens for him/her.
