Abstract: A modular handgun system comprises an elongated universal trigger frame having a barrel locking block, a pair of slide rails, and an accessory rail. The trigger frame is adapted to have a trigger assembly mounted thereto. The system further comprises a grip frame having an elongated channel and a hand grip extending downwardly from the elongated channel. The trigger frame is removably mounted in the elongated channel of the grip frame. The accessory rail of the trigger frame is positioned forward of a forward end of the elongated channel of the grip frame so as to be exposed. The system further comprises a slide and barrel assembly slidably mounted on the slide rails of the trigger frame.

Abstract: A magazine extension for attachment to an open bottom of a magazine tube having a pair of sidewalls, a pair of end walls, and a flange on at least each of the sidewalls at the bottom. The extension includes an extension body having open first and second ends and forward and rear walls. The first open end of the extension body is slidably attachable to the sidewall flanges at the bottom end of a magazine tube. A bottom closure member is removably slidably attached to the open second end of the body and movable between open and closed positions. A latch member is slidably attached to a wall of the extension body to move toward and away from the magazine tube and open ends of the extension body. The latch member releasably secures the extension body to the magazine tube when moved toward the magazine tube and first open end of the extension body.
