Not sure about parts issue but you can find out at Steyrclub.com ... if you ever want to shoot this gun, head over to the NRA range on Wednesday the 27th (or any Wednesday after) and I'll let you shoot mine.
Have you emailed them recently? I am not totally "in-the-know" about the parts issue (my M9 has a lifetime warranty but not through Steyr) but apparently, Steyr's US repair facility has severed ties with them. Again, this is just what I've gathered from Steyrclub.com
