My SW1911 has function issues with .45 TulAmmo. Either the steel used for the casings are incredibly soft or they use some type of laquer on it that shaves off easily. After a few mag fulls, it can sometimes get gritty enough to actually cause a stoppage. The slide can also lock up and become difficult to loosen up again. My Kahr Auto-Ordnance fairs better, but then again the slide to frame fit is much more loose than the SW1911.
Haven't had any issues with 9mm, but then again I've only fired a couple of boxes of it through my 92fs. Still, I've seen enough that I won't be buying it again. People say this stuff is actually Wolff ammo. Personally, I think Wolff is actually superior to this junk if you can believe it.
