Abstract
A firearm that is preferably a revolver has an improved gain bolt construction, particularly for use in larger caliber weapons such as a 44 Magnum revolver. The gain bolt design indirectly assists the hand in particular in the final indexing of the cylinder. The revolver comprises a frame, a hand grip, a trigger, a hammer, a cylinder, and a hand arrangement for operating the cylinder. The trigger is pivotally supported in the frame and has a front flange for operating the bolt which is selectively moveable upon operation of the trigger to permit rotation of the cylinder and lock the cylinder in predetermined positions. The bolt is supported in a compartment forward of the trigger. The bolt includes a forward pivot end, a rear end engaged by a flange of the trigger, and a top lug which is adapted to be selectively locked with a slot in the cylinder in predetermined positions of the cylinder.
