Question for those that carry 1911's
So I have been doing some research on the 1911. Many of you have suggested it as a good carry gun. It seems to be a gun that takes many forms. I have seen it chambered for several calibers. I have seen it in several different sizes. So just what is a 1911 exactly?
This video (http://www.youtube.com/watch?v=nQtT8DEakuc) describes the 1911 by definition as a "single stack, single action" pistol. Hmmm. That narrows it down. *rolls eyes* So I guess the first question is, is this the true definition?
Secondly, a single action pistol, seems would make an interesting carry weapon. I know some suggest carrying with one in the chamber. This would mean that the hammer would be back all day long, right? I realize there are other safety mechanisms in place, such as a grip safety and a thumb safety. Still seems strange to carry a gun with the hammer pulled back. Am I missing something here?
Lastly, what calibers are available (popularly) in a 1911? What do you guys carry (brand, model, caliber) in a 1911? I was at a friends house tonight and he showed me his compact .45 1911. He is offering a good deal on it too. Just not sure I am ready to make a decision yet...
