I just bought my first Glock. It's a Gen 4 19. It was on sale (used) from my local range. They said it was their range gun. It's in excellent cosmetic condition. But, now I'm concerned because as I've done research I've noticed people having issues with gen 4's made in 2010. My ejector number is 1882 and the spring is 034. I haven't shot it yet, but am I gonna have issues?
