I had a small problem with my USP Compact .40 over the weekend. Was out shooting, and the slide for some reason stopped about 7-10mm forward of where it usually does. This was halfway through a magazine. The trigger went sort of loose, and when I checked I pretty much saw something like this:

(Please excuse the terrible line drawings, I didn't take any photos at the range...)
Racking the slide managed to pretty much double-load two rounds. Dropping the mag dropped the second round out, and racking again released the first round. I took off the slide, poked around - nothing obviously wrong. Put the firearm back together, loaded a mag and ran through it at high speed with no problems. Then ran through another slow-fire with no problems. Accuracy wasn't affected.
So, now I'm slightly worried. Any ideas on what could cause this? Have I missed something simple? This USPc has about 2-3k rounds through it. Bought new, never replaced any parts.
