Yeah, I know about that Cane. Had to put them in my Rock Island & (2) American Classics to get them to feed the first round, because any mag I used hung down in the well too low. But I don't think I want to do that in my Colt just to accomodate (4) Chip mags. All my other mags work fine in the Colt, even the cheap ACT mags that came with the RIA & ACs. I'll scrap the Chip mags & buy Tripp mags before messing with my Colt. Of course, I'll save the Tripp internals because they will be good spares to have.
