Firearm having cartridge feed ramp
A firearm having cartridges in a magazine is provided including a cartridge feed ramp disposed on the frame between the magazine chamber and the chamber end of the barrel. The cartridge feed ramp includes a base that is rigidly secured to the frame and a flexible tongue extending upwardly from the base, where the tongue acts as a spring and can deflect relative to the base. During a firing sequence, a top cartridge moves from the magazine in an upward direction toward the chamber end of the barrel, a front of the top cartridge contacts the flexible tongue of the cartridge feed ramp prior to entry by the cartridge into the chamber of the barrel, causing the flexible tongue to deflect outwardly in the direction of the front end of the barrel to assist the feeding of the top cartridge into the chamber end of the barrel.
1. A firearm having a frame, a barrel having a front end and a chamber end, and a magazine having a plurality of cartridges, the firearm comprising:
(a) a cartridge feed ramp disposed on the frame between a magazine chamber of the frame and beneath the chamber end of the barrel, said cartridge feed ramp fabricated from bent sheet metal, comprising:
(i) a base having a unitary flexible tongue, the base rigidly secured to the frame of the firearm; and
(ii) the flexible tongue extending upwardly from the base, the tongue acting as a spring, wherein the tongue deflects relative to the base
(b) wherein, during a firing sequence of the firearm, a top cartridge of the plurality of cartridges moves from the magazine in an upward direction toward the chamber end of the barrel, a front of the top cartridge contacts the flexible tongue of the cartridge feed ramp prior to entry by the cartridge into a chamber of the barrel, causing the flexible tongue to deflect outwardly in the direction of the front end of the barrel to assist the feeding of the top cartridge into the chamber end of the barrel.
2. The firearm of claim 1 , wherein the cartridge feed ramp includes an alignment channel disposed on the tongue, to cause the cartridge to properly align with a longitudinal axis of the barrel as it moves from the magazine to the chamber end of the barrel, during a firing sequence.
3. A firearm having a frame, a slide, a barrel having a front end and a chamber end, and a magazine having a plurality of cartridges, the firearm comprising:
(a) a cartridge feed ramp disposed on the frame between a magazine chamber of the frame and beneath the chamber end of the barrel, said cartridge feed ramp fabricated from bent sheet metal, comprising:
(i) a base having a unitary flexible tongue, said base being generally parallel to a longitudinal axis the barrel, the base rigidly secured to the frame of the firearm; and
(ii) the flexible tongue extending upwardly from the base, the tongue and base acting together as a spring, wherein the tongue deflects relative to the base; and
(b) wherein, during a firing sequence of the firearm, a top cartridge of the plurality of cartridges moves from the magazine in an upward direction toward the chamber end of the barrel, a front of the top cartridge contacts the flexible tongue of the cartridge feed ramp prior to entry by the cartridge into a chamber of the barrel, causing the flexible tongue to deflect outwardly in the direction of the front end of the barrel to assist the feeding of the top cartridge into the chamber end of the barrel.
4. The firearm of claim 3 , wherein the cartridge feed ramp includes an alignment channel disposed on the tongue, to cause the cartridge to properly align with a longitudinal axis of the barrel as it moves from the magazine to the chamber end of the barrel, during a firing sequence.
