My Taurus mags have been very reliable for range (back yard) use to date (over 19K rounds), I've had my magazine replaced by Taurus twice (exellent custumer service) because of heavy wear, at about the 8K round count their done, but they do work fine in the PT1911, as far as other magazine that will work, I believe any 1911 magazine should work on the PT1911, I have a couple Tripp Cobra mags, a couple Chip Mccormick 10 round Shooting Stars, and a couple of checkmate industries Hybrid Lip 8 round magazine that I keep loaded with Double tap 230 gr gold dot defence rounds, the mags that get the most use from me are the stock, and the checkmates.
shoot safe, shoot straight, and have fun
