I just purchased a SA Trophy Match in .40 S&W and although the 8 round mags supplied with the pistol work ok, I just can't seem to get my CMC or Wilson .45 mags to feed 100%. At the range today I notice that the rounds (C.O.L. 1.145") are hanging up about half-way in the barrel, but the case rim was not sliding under the extractor. After a minor adjustment on the extractor, decreasing the tension, feeding seems to improve. I am planning to try some longer rounds (C.O.L. 1.8 - 1.2”), any other suggestions would be greatly appreciated.
