Archie: I will 'third' the hammerhead and kciH, and will advise you to get a new recoil spring kit (recoil spring, hammer spring and firing pin spring) from Wolff Springs. In fact, get a couple of those kits and while you are at it, be careful of the ammo you shoot - some of the Austrian stuff is made for either the CZ52 or the ppsh41/43 and is too hot for the Tok - my suggestion is to get some new Sellier and Bellot ammo for that sidearm. HTH. Mikey.
