Has anyone replaced the fireing pin spring in this pistol? I've had the rear sight off trying to get the decocks out so the spring could come out, but they won't move. I figure there must be a trick to get them out. Does anybody know how they come out?

Well I figured out the trick. Had to disasemble
practicaly the whole gun to get the fireing pin spring out. I mean the whole gun every little piece in the slide.
