I've got one of those pistols, and have shot over 2k rounds through it. The only issues I've had, are an occasional double feed. Which is actually my fault, for racking the slide too slow. FYI, I've only used cheap Blazer ammo so far. What I would suggest, is giving it a good cleaning, and getting rid of all the gunk, from the factory. When I got mines new, the looked like it was swimming in lube. Plus, whatever they slather on the pistol at the factory, is super thick. Which I think could be the cause, of your malfunctions. I also believe, that like any new firearm, it's going to take a couple hundred rounds, to break in.
