Benefits of technology

The present invention is a short recoil locking system for pistols that keeps the barrel in a straight horizontal line during the firing cycle. This system has a simpler design, higher accuracy, and allows for closer tolerances while reducing stress on moving parts. By using an in-line barrel locking technique, the system prevents the long-standing reliability issues of ultra-short barrel pistols that use the tilting barrel locking method. Additionally, the system allows for the barrel to be located deeper in the frame for a lower bore axis to limit apparent recoil and barrel climb in rapid fire.

Problems solved by technology

On those type of handguns, necessary clearances between the interfacing components and motion of the parts when firing contributes to reduce accuracy.
Correction of such problems is possible but requires qualified and expensive gunsmithing.

Embodiment Construction

[0018]The present invention refers to short recoil conversion kits made to replace the tilting barrel locking system on different handguns and to build new ones working on the same principle of a barrel remaining in a straight line during the complete shooting cycle. The first model kit, especially designed for .45 caliber 1911 type pistols, has a round barrel with an elongated front chamber (FIG. 1) inserted from the muzzle end of the slide and a short tight fitting removable bushing 2.3. The second kit, adaptable to many different handguns including the 1911 with a longer dust cover in all calibers and a special wide rails frame in .45 has a flat sided slide and barrel chamber and is installed from the bottom of a bushingless slide (FIG. 13 and 14). Kits are made to fit a specific type of handgun without any modification of the original frame except as it is already the case on 1911 pistols when ramped barrels are used. As both kits use the same type of locking rod / recoil spring g...

Abstract

The slide of a pistol using a short recoil locking breech system is internally machined to house a barrel designed to stay in-line during the complete firing cycle. As the slide goes in battery, a mobile bolt is forced upward to lock the handgun and downward to unlock it to let slide and barrel separate after a shot is fixed.

Description

BACKGROUND OF THE INVENTION[0001]The short recoil locking system is used on most modern center-fire pistols. The most favoured one is still the John Moses Browning tilting, barrel design, either as the original with swinging links of the 1911 Government or the later linkless ramp of the Browning High Power and the numerous models of various makers which followed. On those type of handguns, necessary clearances between the interfacing components and motion of the parts when firing contributes to reduce accuracy. Correction of such problems is possible but requires qualified and expensive gunsmithing.BRIEF SUMMARY[0002]Basic operating principle of the present invention was exposed in my now abandoned application Ser. No. 12 / 802,151 filed on Jun. 1, 2010. The invention relates to a short recoil locking system for pistols in which, unlike on the majority of modern handguns of this type the barrel remains in a straight horizontal line during the complete shooting cycle. This system requi...
