Benefits of technology

"The present invention is an improved semi-automatic handgun that solves the limitations and disadvantages of previous designs. The invention includes an extractor assembly with a first member and a second member that pivots relative to the first member to engage a round of ammunition. The extractor assembly is enclosed in the slide of the handgun and is designed to engage the round of ammunition and facilitate its extraction. The technical effects of the invention include improved reliability, durability, and ease of use."

Problems solved by technology

A jam or misfeed situation may occur when the handgun experiences a problem in the firing cycle.
This type of situation may arise when, for example, the round of ammunition is not properly fed into the chamber or when the spent casing is not properly extracted from the chamber and ejected from the handgun.
In some semi-automatic handguns, a known cause of a jam is a dysfunctional extractor.
However, if the handgun has experienced heavy use, or if the extractor opening is made slightly out of tolerance, the extractor may not always maintain engagement with the rim of the ammunition round.
Either circumstance may result in the ammunition round not being removed from the chamber or in the round not being ejected from the slide.

Abstract

A system and method for extracting a round of ammunition from a semi-automatic handgun having a slide with an opening are provided. A single piece extractor assembly includes an elongate extractor body configured to be disposed in the opening of the slide such that the slide encloses the extractor body. The elongate extractor body includes a first end and a second end. The second end of the extractor body is resiliently biased in a direction toward a round of ammunition and includes a portion configured to engage a rebate on a round of ammunition.

Description

[0001] This application is a continuation-in-part of prior U.S. patent application No. Ser. 10 / 367,682, filed Feb. 19, 2003, which is incorporated herein by reference.BACKGROUND OF THE INVENTION [0002] The present invention relates to an improvement in a semi-automatic handgun and, more particularly, the present invention relates to an extractor assembly for a semi-automatic handgun. [0003] A semi-automatic handgun is designed to fire a round of ammunition. Each semi-automatic handgun operates in a firing cycle during which the round of ammunition is moved from a storage location, such as a magazine, to a chamber in the handgun. The round of ammunition is then fired and the spent ammunition casing, or shell, is extracted from the chamber and ejected from the handgun so that a new round may be loaded for firing. [0004] Typically, each semi-automatic handgun includes a slide that governs the movement of the ammunition round during the firing cycle. The slide moves between a rearward p...
