My girlfreind and brother both own Taurus revolvers. Hers is a Taurus Tracker in .41 mag, 4 inch barrel,his is a .357 in 2 inch barrel I believe. Well, her gun wouldnt revolve once when we were shooting it, actually I believe it was twice. Couldnt turn the cylinder by pulling triger. Dont remember if we tried by cocking hammer. My brothers gun is doing the same thing, with bullets in or empty. WEIRD..Anyone else have this problem?
