Thus far, the 1911. I realize that it's more a category of pistols, rather than a specific model, but there are too many of those that I like to narrow it beyond that. I like the look, the feel, the trigger, the history . . .
However, there are many, many pistols which I have never fired, but which I find very appealing. I will not rule out the possibility that one of them might displace the 1911 one day.
I'm a lawyer, but I'm not your lawyer. If you need some honest-to-goodness legal advice, go buy some.
