The Steyr pistols are cool, but IMO only get one as a "check this out never seen one of these"-guns because you just want one... not to ever run seriously or use as a working gun (even though they're usually up to either/both). I made Master in IDPA my first time with an M9-A1, you could get them from CDNN for ~$300 on clearance back then, and they were so rare/unique that you couldn't find a holster or anything else for them (which honestly, it probably isn't that much easier now). They had a pretty good cult following for a while. They were made incredibly well.
That was ~2008 I think, and back then the Steyr M-series was ahead of the curve and offered a lot of things that Glock or anyone else hadn't really figured out or tried yet, like: more ergonomic grip ergos, nice trigger on a striker-gun, etc, which is all sort of commonplace on poly striker-guns now. The Steyr beat them all to it, but they just didn't take off for whatever reason.
They're a Wilhelm Bubits design, he's designed a bunch of cool unique guns over the years, not the least of which being the Glock 17 (he not-so-arguably had a lot more to do with it than Gaston). The Steyr M-series was his first crack at a "better Glock" after leaving Glock for greener pastures as they say...
Anyways, the design has evolved over the years, the early ones had incredible triggers but weren't always drop-safe... and then later, like with the more recent ones, they've sadly actually had to incorporate some design cues like fancy stippling and such from its contemporaries and play follow the leader, even though the newer striker-crowd were probably influenced by the Steyr in the first place.
IMO they're a cool gun that was ahead of its time in many ways, but don't overpay for one, because there are enough of them out there where you shouldn't have to, and the latest designs may not even be the best examples or the one you want after you start looking into them.
