Abstract
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.
