Gentlefolk, Back from playing with my P220 with a Sig mag. After I cleaned the weapon, I fully loaded the mag with 7 rounds FMJ, released the slide, and found the round did not chamber. Works fine with six rounds in the mag, but that 7th round really, really binds the cartridges. i needed to push the 7th cartridge out with a tool to get it out of the mag. Odd, because everything was fine at the range.... Ideas? I figger I need ro tear down the mag and see if something got bent, but I am not that hard on mags....????
