I had a chance to shoot a 1911, .45ACP built by Pistol Dynamics/Paul Liebenberg. Ran about 75 rounds through it during a phase of an advanced pistol class. I took a couple of pics, but I'm having problems posting the second pic.
Pistol has matte blued finish on a 70 series Colt that the owner supplied Paul. The rear sight is of Paul's design and is a close copy of the Novak, the front post has a tritium insert. The barrel bushing, magwell, grip safety, slide stop were Paul's design and manufacturered by him. Front strap was 20 lpi, sharp! Like most of his pistols, Paul recut the recoil spring tunnel. The top of the slide was serrated (20LPI) and covered the entired rounded part of the top of the slide. The trigger was crisp and light, the owner and I prefer a little heavier trigger on a carry gun, but this gun is too beautiful to be carried.
I didn't get to shoot it for accuracy at longer range, I mostly shot it at 25 yards or less. All shots were fired offhand, some while moving. The pistol didn't like my old CMC Power mags, but functioned 100% reliable with Wilson 7 and 8 round mags (new or old).
