I've got a fairly new 9mm Colt Defender with around 500 rounds through it. It started 'stove-piping' and it was suggested that the extractor was the problem. I replaced it with a Wilson Combat 'tougher than nails' extractor. I fired a few clips through it and it ran fine. Now it is 'stove-piping' almost every round. :huh::huh: I have no problem sending it back to Colt; just hoping it's a simple problem that I can, or someone locally can, easily fix. Any suggestions? Thanks, Frog.
