I've held one Steyr in my life, the M9A1, and it may have been the best feeling gun in my hand yet. This was 2 years ago and I didn't have the money for it that weekend. I feel the urge to go gun shoppin and the Steyr came to mind. I've pretty much forgot about it since I held it unfortunately or else I would have bought one by now. I have a couple questions.... I've done a little research and saw they have the( I'll use .40 as example) m40A1, s40A1, l40A1,and c40A1. I assumed the c40 was compact but apparently the s40 is the compact? Or maybe they both are. I wasn't able to find the difference between the c40 and m40. Also does steyr make it in .45? I've never seen one fired in person, nor have I talked to anybody about their experiences with Steyr. Usually youtube tells me everything I need to know but not in this case.lol If anyone can guide me with a bit of info on these guns that would be great. If I'm able to find one I promise some pics!
