I was shooting my PT945 Friday in DA and SA and my friend was shooting his really expensive Kimber 1911 (don't know the specific model). I noted how accurate he was in SA and asked him to try DA. The gun wouldn't do it. I have a Colt 1911 but haven't shot it in a while and can't remember if it's the same way. I don't think I could conceal carry a .45 with a round chambered, hammer cocked and the safety on. I am more comfortable with the PT945; round chambered, hammer released and safety on. Seems like way less chance of shooting a round in my leg.
