The Para LDA would be an option, though the 1911 purists out there will tell you that it's not really a 1911. I guess that depends on how you define a "real" 1911.
The Para LDA is a 1911 pattern pistol that uses an operating mechanism much like the Glock "safe action" system. Cycling the slide actually preloads the striker, or "cocks" the gun. Despite the "Light Double Action" name, the LDA is not a true double action design. It's a single action with a huge amount of take-up on the trigger. If you have a misfire, you have to execute a tap-rack-bang sequence, just like with a traditional single action 1911 (with a DA autoloader, you could just pull the trigger again).
I carry a Para Ordnance CCW, which is a commander length barrel/slide (4.25") on an officer frame, and the LDA trigger system. I was transitioning to 1911s from Glocks, so it was easier for me than going straight to cocked and locked. I may someday go all the way to C&L.
The LDA does indeed have a manual safety (along with the 1911 grip safety), which sets it apart from the Glock. Whether you use it or not is up to you. One could argue that it's not necessary thanks to the long trigger travel of the LDA. I use it because I shoot single action 1911s in action pistol, and I'm in the habit of sweeping the thumb safety off, anyway.
You should also know that the LDA thumb safety works a little different than a traditional 1911 thumb safety. It locks the slide and disconnects the trigger. Thus, you can pull the trigger with the safety on, but the gun won't go bang. The fact that the trigger isn't locked confuses some people into thinking that the safety is off. I figure that will give me an extra few seconds in the unlikely event some BG gets a hold of my CCW piece.
