I have 3 1911's. All are reliable. Oldest is a S&W lightweight commander that has 5000+ rounds through it. Newest is a Dan Wesson Vigil (lightweight commander) and has been reliable with the 500 rounds put through it . The last one is a Tisas A1 that has been reliable for 600+ rounds. All are 45 acp. Dan Wesson is my favorite carry and night stand gun.
