Well, I picked up my Tracker (.357 SS), yesterday and immediately went out and gave it a try. Still trying to get my sight adjusted the way I want, but otherwise, very happy. I ttried several different bullet weights and mfgs, found the 125 gr loads to be pretty accurate, the 110 gr loads made very impressive flashes!
That is I guess, due to the porting? Anyway, the grips worked great at softening the felt recoil and when I relaxed and didn't flinch, the gun grouped very nicely. I need lots more practice to fully realize the gun's potential, but so far, it is a winner.
