Embodiment Construction

[0027]An example Heckler and Koch type pistol 20 for use with present invention embodiments is illustrated in FIGS. 1-2. Specifically, firearm or pistol 20 includes a frame 1, a slide 2 mounted on frame 1, a barrel unit 3A, and a recoil spring mechanism 5. Frame 1 includes a trigger mechanism 18 with a hammer 16, and a handle or grip portion 19 housing a magazine 21 for storage of one or more cartridges 28. Slide 2 is mounted on frame 1 and is adapted for reciprocal longitudinal movement on the frame in response to firing of pistol 20. Barrel unit 3A includes a chamber portion 41A and a barrel portion 43A. The chamber portion underside or bottom surface includes forward understations or projections 9, 25 and a rear understation or projection 26. Projections 9 and 25 adjoin each other with projection 25 basically forming a shoulder (e.g., or non-planar geometry) with the bottom surface of barrel portion 43A, while rear projection 26 is separated from front projection 9 by a suitably ...

Abstract

The present invention embodiments provide a barrel component with the forward under-portion of the barrel configured in various manners. For example, the configurations may include an upward displacement, or angular or radial contouring, of barrel material at the forward underside of a barrel component understation or projection. These configurations provide clearance to allow the barrel to bypass frame-mounted impediments to blank-fire, and permit proper timing and coordination of rearward barrel motion under impact of the recoiling slide and the resultant barrel drop into recoil position without interference with, or re-capture by, the reciprocating slide component. In addition, the blank-fire barrel may be configured to incorporate a laser device for marksmanship training and conducting realistic tactical training exercises.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority from U.S. Provisional Patent Application Ser. No. 60 / 905,033, entitled “Blank-Firing Conversions for Semiautomatic Pistols and Method of Repetitive Blank Fire” and filed Mar. 6, 2007, the disclosure of which is incorporated herein by reference in its entirety.BACKGROUND OF THE INVENTION[0002]1. Technical Field[0003]The present invention embodiments generally pertain to firearms. In particular, the present invention embodiments pertain to semiautomatic breech-locked, recoil-operated pistols configured to produce reliable and repetitive blank-fire operation.[0004]2. Discussion of Related Art[0005]Conventional semiautomatic pistols designed to discharge high-pressure cartridges (e.g., 9 mm Parabellum, 0.357 SIG, 0.40 S&W, 10 mm, and 0.45ACP cartridges) typically employ a breech-locked, recoil-activated mechanism that is derived from the BROWNING and COLT / BROWNING family of firearms. In this mechanism, the pis...
