Hmmm,
I don't know who told you that Steyr was working on a full-size, but I'm all over the various gun forums and google and I haven't heard a single rumor about a full size Steyr. As for .45acp there were some rumors that Steyr was thinking about it, but they seem to be just rumors as nothing solid has come out yet. For some reasons the Europeans just aren't nuts about. 45 caliber pistols. My guess is that if the MA1 series takes off in the U.S. and sales are huge they would go for the .45 caliber, but for now I think they're just trying to concentrate on selling what they've already put out there the 9mm, .357 Sig, and .40 S&W.
