My cousin had one. The Colt marked pistol that was DAO. Got it at a gun show.
He eventually screwed up and shot himself in the hand with it one night racking the slide (you have no idea how many times I'd told him not to hold a pistol with his right hand across his chest while racking the slide to the rear with his left hand over the muzzle.) That big old ugly .40 S&W hollow point went into the palm of his hand near the bottom and traveled up his arm to just short of the elbow before exiting and hitting the wall by the head board of his bead. He was very lucky as it must have just traveled between the skin and the muscle. He went to the emergency room and they treated him and sent him home. No other issues from it.
Then he married an evil woman who had credit card bills out the ying yang he didn't know about till after they were married. He ended up selling most of his guns trying to pay off her credit card bills and keep her from losing her house. When he finally got her back on solid financial ground she accused him of assaulting her and got him thrown in jail and then got a restraining order on him so he couldn't go back to the house he'd been paying for. During the trial it came out the gun he supposedly "pointed at her" was a rifle in the case he was carrying out the door to go to a shooting range. The court convicted him anyway but then, on the appeal they dropped the charges and over a year or so of fighting with them about it they wiped his records clean and everything is back to normal - but he never got his money or his guns back and lives in another state now.
Several nice/rare guns left his possession forever, as well as most of his bank accounts. I've got a feeling he'd get married again though. Some people never learn.
I shot it, once, when he brought it home with him. Had the nice blue box, the Colt owner's manual, the Colt name/logo on it. Seems like, on the bottom of the frame, it was marked CZ, but that's been a long time ago.
The story, we heard around here, was that Colt was going to shut down it's handgun manufacturing facilities in the US (combination of mismanagement and political pressures) and have "Colt" handguns made overseas for sale in the US. I know I'd just bought my Colt Series 80 Government Model in stainless steel a few months prior to that for $495 and right after than announcement the prices on the same pistol jumped up to over $900 in the local gun stores. I remember being at one of the bigger gun stores in the area and hearing people come in and ask about Colt guns only to be told they'd sold out and didn't know when they might get another shipment in.
