I can't speak for the TM, I've never owned one, but I have a KSC glock 17 and I wouldn't trade it for the world. Only thing I can say is throw on a metal slide and upgraded recoil spring/rod and you'll be set for life! REALLY nice weight, hard, crisp blowback and runs awesome on propane. Very nice look, feel, weight and accuracy. NEVER had a problem with her in my life. As I said before, I wouldn't trade her for the world.
