Sounds like ammo. I've shot thousands of WWB 9mm for years with no problems but lately, I've had some quality problems with it too.
Went to the gun show yesterday and picked up a new Pf9. Been looking for a new pistol for a little while and picked one up for a pretty good price. I put about 30 rounds through it last night no problem. Cleaned it up and went out to shoot with my brother today. About the fifth round of Winchester white box (cheap, I know) The bullet fired, but didn't exit the barrel or eject the casing. Pulled it apart and the inside had powder all over, but the bullet just fell back out. I'm guessing this was probably the result of cheap ammunition, but I wanted to see what you all thought. But, other than that I like it so far.
