Abstract
A revolver with light-weight firing control housing includes a cylinder frame supporting a rotatable cylinder defining a plurality of cartridge-receiving chambers and a firing control housing made of a non-metallic material. The firing control housing attaches to the cylinder frame and supports firing control mechanism components, such as a trigger and a pivotable hammer actuated by the trigger. In one embodiment, the firing control housing may be made of a polymer and the cylinder frame may be metal.

A revolver with separable light-weight firing control housing comprising:
- a cylinder frame supporting a rotatable cylinder defining a plurality of cartridge-receiving chambers, the cylinder being received in a complementary configured opening defined by the cylinder frame;
- a separable firing control housing made of a non-metallic material and removably attached to the cylinder frame;
- a firing control mechanism comprising a hammer pivotably supported by the firing control housing for discharging the revolver;
- and
- a pair of forward facing concave shaped bearing surfaces disposed on the firing control housing that engage a mating pair of rearward facing complementary configured convex shaped bearing surfaces disposed on a rear portion of the cylinder frame for mounting the cylinder frame to the firing control housing;
- wherein the engaged pairs of concave and convex bearing surfaces are operable to absorb and distribute recoil forces from discharging the revolver to the firing control housing.
A revolver with separable light-weight firing control housing comprising:
- a metal cylinder frame having a rear and defining an opening receiving a rotatable cylinder, the cylinder rotatably supported in the opening by the cylinder frame and defining a plurality of cartridge-receiving chambers;
- a separable firing control housing supporting the cylinder frame, the firing control housing being made of a non-metallic material and including a rear grip tang configured for mounting a hand grip;
- a trigger pivotably mounted to the firing control housing;
- a spring-biased hammer pivotably mounted to the firing control housing, the hammer being movable to a cocked position by the trigger;
- and
- a pair of laterally spaced forward facing concave shaped bearing surfaces disposed on the firing control housing that abuttingly engage a mating pair of laterally spaced rearward facing complementary configured convex shaped bearing surfaces disposed on the rear of the cylinder frame for securing the cylinder frame to the firing control housing;
- wherein the engaged pairs of concave and convex bearing surfaces are operable to absorb and distribute recoil forces from discharging the revolver to the firing control housing.
A method of assembling a revolver having a separable light-weight firing control housing comprising:
- providing a non-metallic firing control housing;
- mounting a trigger to the housing;
- mounting a hammer to the housing for pivotable movement between a cocked and an uncocked position;
- providing a metallic cylinder frame having a rear end and rotatably supporting a cylinder having a plurality of cartridge-receiving chambers in an opening formed in the cylinder frame;
- and
- abuttingly engaging a pair of laterally spaced forward facing concave shaped bearing surfaces disposed on the firing control housing with a mating pair of laterally spaced rearward facing complementary configured convex shaped bearing surfaces disposed on the rear of the cylinder frame for absorbing and distributing recoil forces from discharging the revolver.
