I believe I have found the perfect 1911 magazine. In addition to holding more rounds it feeds everything without a single problem. I have a number of different 1911 magazines from mil surplus to Colt Gold Cup national match magazines to the ultra high dollar ones. The only one I have found so far that will feed any combination of bullet styles and or a mix in the Brownells 8 shot with the bumper on the bottom.
This mag will flawlessly feed the Magma 200gr SWC and 185 Magma SWC bullets which no other mag would feed without problems.
