Abstract
A firearm comprises a frame and firing control housing insert detachably mounted in the frame. A rear securement feature includes a locking slot formed in the rear wall of the insert engaging a locking protrusion formed in the rear wall of the frame which retains the rear portion of the insert in the frame. A front securement feature includes a rotatable pin inserted through holes in the insert front portion and frame. A radial retention protrusion on the pin is interposed between the insert and frame defining an interlock feature. The pin is rotatable into a first position wherein the protrusion passes through a complementary configured frame aperture allowing the pin to be removed, and a second position wherein the protrusion is not aligned with the aperture to engage the frame and prevent pin removal.

A firearm with removable firing control housing insert, the firearm comprising:
- a longitudinal axis;
- a frame including a pair of right and left sidewalls, a rear wall extending transversely between the sidewalls, an open top, and an axially elongated cavity accessible through the open top;
- an axially elongated firing control housing insert including a front end, a rear end, and pair lateral sidewalls extending between the ends;
- the insert detachably mounted in the cavity and configured for holding firing mechanism components, the insert being removable from the cavity through the open top of the frame;
- an elongated locking slot formed in a rear wall of the insert engaging a forwardly projecting locking protrusion formed in the rear wall of the frame, the locking slot and protrusion operable to retain a rear end of the insert in the frame.
A frame and firing control housing insert assembly for a firearm, the assembly comprising:
- an axially elongated firing control housing insert removably inserted into an upwardly open cavity of a firearm frame, the insert including a longitudinal axis, a front portion configured for mounting a trigger assembly of the firearm, a rear portion configured for mounting components of a firing mechanism of the firearm, and a pair of spaced apart struts connecting the front and rear portions;
- a rear securement feature comprising a locking slot formed in a rear wall of the insert engaged with a complementary configured locking protrusion formed in a rear wall of the frame;
- a front securement feature comprising a transversely mounted rotatable retention pin inserted laterally through a first pair of holes in the front portion of the insert and a second pair of holes in the frame;
- a radially extending operating lever arranged on a first end of the pin for rotating the pin;
- and
- an interlock feature comprising a radially extending retention protrusion on the pin interposed between the insert and frame proximate to a first hole of the second pair of holes in the frame;
- the pin being rotatable between a first removal position wherein the protrusion is aligned to pass through a complementary configured frame aperture allowing the pin to be removed from the frame, and a second engagement position wherein the protrusion is not aligned with the aperture to engage the frame and prevent the pin from being removed from the frame.
