Colt 1911 Model 70 Mag Problem
This is a late post but I found the thread in a search and I have the exact same problem with my Series 70 and Wilson Combat and Chip McCormack 8 round mags. The gun has been customized and is used for Single Stack and CDP with 200 grain LSWC. I should add if it matters that it dates from Vietnam years and started as my sidearm out of the box. The custom work is only a couple of years old (trigger job, barsto barrel, slide tightening, fiber optics with bomar sights, extended mag release, mag well, etc.). Essentially all of the internals have been replaced. The gun is very accurate and with reliable after playing with loads. When I load a mag with the slide closed I have to bang the Wilson (not ETM) in for it to seat and substantial pressure is needed on the mag release to eject it. The McCormack is even worse. Take out a round and they both seat easily as do all of my 7 round mags. But If I insert either 8 round mag with the slide open it will easily seat and release. Had some issues in a match yesterday with the Wilson. Have not tried Tripp, Mec-Gar or Les Baer. The loss of the extra round hurts in single stack, a bit less in CDP. Should I just order a set of Les Brown, ETM and Mec-Gar from Brownell and one from Tripp to see if any work or just live with 7+1? I thought my gun was somewhat unique so I was surprised to see that it is a somewhat common issue. The final option is I buy another STI in .45. (have one in 9mm) which has the obvious advantage of adding another gun. But the Colt has sentimental value and other than the mag issue I have it where I want. Thanks for any help or comments.
