I can tell you, the PT911 I used to own had better accuracy than I was capable of. In rapid fire, at 7 yards, I got 14 out of 15 shots into the head region of a silhouette target. And the one that was outside the head, was JUST outside the head.
I don't know why people think the 1911 is too big for CCW. I typically carry one of three pistols. Either my PT92AFS, my EAA Witness (full size) or my Para-Ord P1445. I rotate between those three on a regular basis.
But I'm not a small person, so maybe it's easier for me to hide them.
