Heck yes, not only would I buy one, but I’d be rushing down tomorrow to give my dealer a deposit on the first one he gets.
However, I don’t care much for the double-stack .45 idea (too bulky). Keeping the great feel and pointability of the current Steyr grip is much more important. That’s what makes the M9/M40 series so unique. If the new Steyr .45 emerged as a big, fat, Glocklike .45, I wouldn’t be so interested (heck, in that case, I might as well just buy myself a stupid Glock).
1911 magazine compatibility is okay, but not that important to me. Hey, if I can afford a new Steyr .45, two or three spare magazines for my new companion isn’t going to break me.
Too bad it’s all just a pipe dream for now . . .
