The present invention generally relates to firearms. More specifically, the present invention relates to firearm parts.
The assembly of firearms from parts instead of purchasing a complete firearm has become popular with the purchasers of firearms. It has become a hobby that allows the firearm to be customized with the desired features by the purchaser. When a purchaser buys a completed firearm from the dealer, that purchaser usually ends up spending more money on customizing the firearm, while discarding parts that originally were part of the firearm. Popular changes to completed firearms are trigger replacement, barrel replacement, sight replacement and weight reduction modifications.
The trend is to have firearm receivers and frames available for sale that a purchaser can buy. Then, the purchaser buys the other required firearm parts separately to assembly the firearm. The receivers and frames are traditionally made from metal, but now are also being made from a polymer material. Receivers and frames made of the polymer material sometimes require additional parts to be used with the parts to be installed. Typically, these parts are made from metal and can include such components as slide rails and receiver stiffeners.
It is an object of the present invention to provide one component that adds both a rail and a trigger mechanism receiver as one part to be assembled in a frame or receiver.
The present invention provides a pistol with a frame having a rear grip, a trigger facility forward of the grip and an upper surface. An elongated slide is connected to the frame and operable to reciprocate along the upper surface. The frame defines a rear recess open at the upper surface. An insert is included having a major portion removably received in the rear recess and having a frame rail extending from the major portion above the upper surface. The frame rail is adapted to connect with the slide to constrain reciprocation.
The right side 14 and the left side 16 each include a front contact edge 26 and a rear contact edge 28. The rear contact edge 28 of both the right side 14 and the left side 16 includes a trigger housing pocket radius 30 which curves along the rear contact edge 28 of each of the right side 14 and the left side 16. The rear contact edge 28 of both the right side 14 and the left side 16 each have a rear straight edge 32 from the trigger housing pocket radius 30 to the cross member 18. The right side 14 and the left side 16 each include a pin hole 34 near the bottom of the right side 14 and the left side 16. The front contact edge 26 of both the right side 14 and the left side 16 each include a front straight edge 36 on a front of the right side 14 and the left side 16. The front straight edge 36 and the rear straight edges 32 extend from the cross member 18 at an angle and are parallel to each other. The right side 14 includes an index tab 38 along the front contact edge 26, where the index tab 38 extends into the housing receiving area 20.
The trigger mechanism housing 22 is shown inserted into the housing receiving area 20 of the rear rail insert 10 in
The rear rail insert 10 is a component inserted into a pistol frame 12 that serves two key functions in a single component. The rear rail insert 10 allows the trigger mechanism housing 22 on to be inserted in between, and then locked in in place using a pin 56 that is inserted into the pistol frame 12. The rear rail insert 10 also serves as a guide with slide rear rails 24 for the pistol slide 13. The end user, after acquiring a pistol frame 12, takes a trigger mechanism housing 22, inserts it into the rear rail insert 10, then slides it down into the appropriate rear section of the pistol frame 12. A steel or plastic pin 56 is then driven through one of the pin holes 52 in the frame and into pin holes 34, 54 that align to each other, in the rear rail insert 10 and the trigger mechanism housing 22 to seat and affix the rear rail insert 10 and the trigger mechanism housing 22 to the pistol frame 12.
While different embodiments of the invention have been described in detail herein, it will be appreciated by those skilled in the art that various modifications and alternatives to the embodiments could be developed in light of the overall teachings of the disclosure. Accordingly, the particular arrangements are illustrative only and are not limiting as to the scope of the invention that is to be given the full breadth of any and all equivalents thereof.
This application claims the benefit of U.S. Provisional Patent Application No. 62/505,309 filed on May 12, 2017, entitled Pistol Multi-Functional Rear Rail Module, which is hereby incorporated by reference in its entirety for all that is taught and disclosed therein.
