I have a Les Baer SS Custom Carry that has a problem feeding rounds from the mags that came with it. Several times a live round gets pushed up and caught by the slide as it comes forward putting a dent in the casing. This doesn't seem to happen with Wilson Combat or Chip McCormick. I called and was told it could be that the springs in the mags are too tight still. Load the magazines a day or 2 before shooting and use America Eagle ball ammo. Still a problem. Suggestions, besides use different mags? Could it be the gun or somehow modify these mags? Another thing I was told is to use mags with plastic followers and not metal like the McCormick's. Why would that be?
