I'm not holding my breath, but I'll even take one that works most of the time....lol.
Have you tried any full size 9mm 1911 pistols? I have full size 9mm 1911 pistols by Springfield, Colt, and Kimber that all have been 100%. I have not shot them as much as I shoot my 45 Auto pistols, but they have never given me any problems. I would be curious to hear if any of the 1911 gurus around here have found any differences between full-size and shorter 9mm 1911 pistols as far a reliability is concerned. I seem to recall that you have been trying one that is not full size.
