If so, that's commonly called a "failure to feed". The other thing I would recommend doing besides cleaning thoroughly and shooing it more is mark your magazines (write a number on the baseplate with magic sharpie or something). Most semi auto handgun failures/stoppages are the result of a bad/faulty magazine, so if it happens several more times, but only with a certain magazine, you know your culprit is a paticular magazine and not the gun itself.
Good luck, hope you get it ironed out.
Oh and welcome to the forum.
