I have a pt1911SS that I absolutely love. Just about 1000 rounds mixed of jhp and fmj with not one failure. The newer ones seem to have the bugs worked out. One that I handled in a shop had the thumb safety problem where if you'd grip it tight it would flip the safety on, but that was an older heine sighted model. The others with the current novak 3 dots didn't have that problem nor does the one I have.
I really love the gun and am glad I bought it.
I recently bought an mp9c for my wife and love the whole mp series, but since you already have some of those and have always wanted a 1911 anyway, my vote was to go with the Taurus.
