Abstract
A pistol chassis is disclosed which may include a lower housing, an upper housing, a proximal enclosure, a distal sleeve, and a proximal accessory. The distal sleeve, lower housing, and upper housing may be secured together to form a tubular member for receiving a pistol. The lower housing further may include a distal segment, a proximal segment and an intermediate segment. Time distal segment may include a pistol frame receptacle and a trigger guard enclosure. The proximal accessory may be a folding stock. The pistol chassis may house a pistol to produce a firearm apparatus.

A pistol chassis comprising:
- a lower housing which comprises a distal end and a proximal end, the proximal end being spaced from the distal end along a first longitudinal axis, the lower housing comprises
- a distal segment comprising
- a pistol frame receptacle which comprises
- a starboard side rail and
- a port side rail, the starboard side rail and the port side rail being configured and dimensioned to interlock with a housed pistol frame to precisely and securely position the housed pistol frame in alignment with the first longitudinal axis, and
- a trigger guard enclosure which comprises
- a first wall including a first fastener receiving hole,
- a second wall spaced from the first wall, the second wall including a second fastener receiving hole, and a third wall disposed between the first wall and the second wall,
- a trigger guard seat comprising a trigger guard contact surface, a spring guide surface spaced from the trigger guard contact surface, a first side wall, a second side wall, a spring guide extending from the spring guide surface, a compression spring disposed around the spring guide, an elongated slot extending from the first side wall to the second side wall, and a trigger guard retention pin, the trigger guard retention pin being disposed in the first fastener receiving hole, the elongated slot, and the second fastener receiving hole,
- a proximal segment comprising a blocking element and a track,
- an intermediate segment situated between the distal segment and proximal segment, the intermediate segment comprising a lower opening for receiving a pistol and a starboard opening for passage of fired ammunition casings, and
- a proximal enclosure connected to the proximal segment, the proximal enclosure comprising a projection, a clamping surface which is configured and dimensioned to interlock with a pistol grip dovetail, and a proximal latch for selectively locking the proximal enclosure to the intermediate segment, the proximal enclosure being telescopically received on the proximal segment, the projection being positioned in the track, and the clamping surface being disposed opposite the pistol frame receptacle.
