Yeah, both my carry guns are 1911s. Single action. Meaning pulling the trigger will only do a single action- drop the hammer. Pulling the trigger on a double action pistol first cocks and then drops the hammer. One of the virtues of the 1911 is the very short, light, straight trigger pull- about 1/8 of an inch straight back. It was for this reason that the US Government required the grip safety to be added before they would adopt it as the standard sidearm, almost 100 years ago. A lot of peaple have told me that it is perfectly safe to carry a 1911 "cocked and locked" (condition 1), as the thumb safety would have to move or fail AND the grip safety would have to be depressed or fail, AND the Trigger would have to move or fail. But...........
...........Prior to getting my CHP I carried at home for months with dummy ammo, practicing my draw stroke, and getting used to carrying. I had a 5" 1911 in a suede IWB holster at the 5 o'clock position, with a forward cant. In all those months, the thumb safety moved once. That was one time to many for me. The thought of a powder gas enema ........ I'd rather not think about that ........... SO..........
.......I could carry in condition 2 (hammer down on a round in the chamber- the way double action pistols are carried), but manually cocking a 1911 with your thumb is awkward, slow and might allow for your thumb to slip, ............ not only that, a light blow to the hammer (as in dropping the gun- easy enough to do w/o your thumb wrapped around the grip.....) will fire the chambered round.
...........or I could carry in condition 3 (hammer down on an empty chamber. It worksfor the Israeli IDF(although they do it differently than I do- they present the pistol on its side, and pull the slide back w/ finger and thumb, then right the pistol). If you practice it, it takes like 2/10ths of a second, and that's not an extra 2/10ths- you don't grab the slide and pull it back. Rather, as the gun is coming up, the off hand goes over the top, squeezing the slide between the 4 fingers and the palm. As the pistol is shoved forward to arms length, the slide stays in place momentarily, and upon release, the round is chambered. The only extra time involved is moving your off hand to wrap the strong hand. And that's not really extra time either, as while thats happenening, your strong hand and you eye are putting the front sight on the CM of the target. It sounds complicated, but try describing how to ride a bike. With practice, you don't even think about it.
There is no free lunch- this system has its disadvantages. It requires 2 hands (or a 1911 with a stadard -as opposed to full length- guide rod and a solid object, like a steering wheel). And point shooting from the hip is not possible( which I'm not a fan of anyway-I am responsible for EVERY bullet that leaves my gun.)............
