I have a PT 1911. It did have some problems where the thing would lock up and the trigger could not be pulled. We traced the problem to the Taurus hammer with the safety locking screw. Replacing the Taurus hammer and sear with a Wilson combat hammer and sear seems to have eliminated the problem, at least through several hundred rounds since the replacement. Another 1911 which deserves serious consideration is The RIA. My son has a RIA compact and it has the best trigger of any gun I've ever fired, and that includes a couple of match grade Colts.
