I have considered a 1911 in 9mm several times over the years.

The closest thing I have to a 1911 now is an Astra A-70 in 9mm, which is sort of a 3/4 size 1911 - single action, single stack, cocked and locked carry - and I love it. I alternate carrying it and my Shield 9mm.

I already have a full-size 9mm, a Star 30MI - a double stack "Krunchen-ticker" (so called by the late Colonel, who despised 9mm double-single actions), which I used to carry in a shoulder rig back when I was younger. It is accurate, all steel, and very heavy. It would double as a truncheon if the 15 rounds it carries are not enough. No way I'm getting rid of it, altho its only duties now are range and nightstand.

I think if I did purchase another full-size 9, it would probably be a CZ-75. I missed the opportunity back in the 90's to purchase one of them reasonably ( oh, to have back a few decisions...).

But, the Ruger 1911 in 9mm is very tempting.
