Excellent product. - Pachmayr Rubber Magazine Bumper Pads

The best bumper solution for colt M1911 magazines, period. I have installed these bumpers on both 7 and 8 round magazines for my Series 1980 Colt 45 ACPs (I own 2, one being the RG model) and they are great. Both my Colts have magazine well extensions and the magazines with the bumpers sit almost flush. They ship with the template and screws and the drilling is a simple operation, even without a drill press. The bumpers themselves are light, hard rubber, not cheap plastic that can break, or metal that adds weight to the magazine. Perfect for practice or competition where your magazine will hit the ground/pavement.
