I've got an M40 and I love it.
The sights do take some getting used to, but they work well and aquire fast (hell, you have people yanking the three dot sights off their CCW guns and putting big dot Express sights on them and nobody makes fun of them ... same principal).
As for the safety issues, I read those debates on TFL and here on THR thoroughly and frankly the "Steyr is safe" camp made a much more compelling argument backed up with math and science and such then the "Steyr is unsafe" camp did. I'm sure my Steyr is as safe as any other well maintanied carry gun out there, and is at least as safe as a Glock (if not moreso because of the manual safety).
As soon as I can scrape together the money I
will buy an S40 to replace my Makarov as my primary CCW gun (the grip length of the M40 makes it print too much ... although in heavy coat weather it will be my choice over the Mak). Grip length issues aside, the Steyr M is probably the most concelable doublestack handgun of its size out there ... much better then that Glock 23 brick
(lots of rounded corners and a real thin grip for a doublestack makes a world of difference). Even though its larger then my Makarov it is more comfortable to carry.
Other then when shooting Wolf ammo, Its been reliable and accurate ... I find it more accurate and comfortable to shoot then a Glock 23 (which is the closest gun to its size and design). The ergonomics are excellent (I suspect that Mr. Bubbitz and I wear the same glove size) as a result the recoil from my .40 feels more like a 9mm.
Its a breeze to takedown for cleaning (easier then the Kahr MK40 I used to own, and easier by far then my Makarov).
The only downside to the Steyr seems to be the availablity of parts and such, which I understand may not be an issue much longer.
It would be nice to have a few other model choices (I understand an L series may be coming out eventualy ... and of course .45 and 10mm versions would be much appreciated).
Oh and I'm Zundfolge (aka Mike) in Colorado Springs
