IMHO the integrated feed ramp that Para developed solved this problem. I have had two of them and both guns have fed every conceivable nose configuration of bullet designed to be shot in the 1911, including some that were not. Had JMB had modern CNC equipment to work with this is one thing I am certain he would designed into the package.
That said my $325 Norincos with the traditional feed ramp set up has reacted the same way with all nose types as well with 7, 8 and 10 rd mags from STI, Norinco, McCormick, Colt, Metalform & Para. The pistols come with throated feed ramps.
