I have a Kimber Pro Carry II in 40 S&W that on the last round in the mag the shell will not feed correctly.* The nose of the bullet will jump straight up and the rim of the case is still in the mag.It almost looks like a stovepipe with a loaded shell.* It does it all three of the mags that I have.* This is a fairly new gun, only around 200 rounds.* Any ideas or help is appreciated.
