I've shot thousands of rounds of Wolf, Tula/Herter's and Silver/Brown Bear 9mm out my various Glocks (19/17/34's) in practice, classes and IDPA/USPSA club matches with no issues except the occasional FTF.
Like others said its dirty, lower velocity and hard primed but I've found it reasonably accurate and reliable for inexpensive, steel-cased ammo. It's GTG in my book.
