Ok. Just got back from my first trip to the range with my new G19 Gen4. After the first shot, the gun had a FTF. The slide went back, ejected the shell, then the next round got jammed up. I then cleared the gun, tried again, and when I cocked the slide back to load one in the chamber, it happened again. I then tried being more aggressive and really snapping the slide back, then it worked. After that, it shot perfectly for 100 rounds. Is this something common with a brand new gun? Should I be concerned? Maybe it just needed breaking in?
