Ok. work reliably with minor issues - Mec-Gar 1911 .45 ACP 7-Round Pistol Magazine

When loaded with 10 rounds the 9th and 8th rounds dont sit in the correct orientation which allows the rim of the case to be loaded to catch the rim of the round below it. While they feed reliably this causes the bottom case to move forward and the nose is outside the profile of the magazine. It will feed ok if your ramp is correct. However if you have to drop a magazine with rounds in it, after you fed one into the chamber, the top round will be dropped out of the mag well when the magazine is removed. An annoyance but still an issue.
