Abstract
An apparatus and method for modifying a handgun to accept an optical sight comprises a modified slide mechanism adapted to include a flat recessed rear section configured to receive an adapter plate for mounting an optical sight. Various embodiments of the adapter include modified internal components used to replace stock components what will no longer fit within the modified profile of the slide mechanism. Replacement of the slide mechanism and associated internal components will allow a user to add an optical sight to an existing handgun.

A conversion kit for adapting a firearm slide to receive an optical sight, wherein the firearm slide includes an internal extractor, the conversion kit comprising:
- a slide having a flat rear section recessed into a top portion of the slide and positioned below a topmost surface of the slide, wherein the flat rear section comprises:
- a first set of mounting holes;
- a firing pin block opening;
- and
- an extractor pin opening;
- an adapter plate configured to be mounted within the recessed flat rear section by the at least one mounting hole, wherein the adapter plate comprises:
- a second set of mounting holes aligned with the first set of mounting holes;
- at least one mounting bus disposed along a top surface that is configured to align the optical sight with the adapter plate;
- and
- at least one receiving port disposed along a top surface that is configured to connect the optical sight to the adapter plate;
- and
- a firing pin configured to be positioned within the slide, wherein the firing pin comprises a forward cut out section for receiving the extractor disposed proximate a forward end of the firing pin, wherein the cut out section comprises:
- a notch configured to engage the extractor and disposed along a forward portion of the forward cut out section forming a substantially perpendicular surface relative to a longitudinal axis of the firing pin;
- and
- an angled end surface disposed along a rear portion of the forward cut out section.
A firing pin for a firearm adapted to receive an optical sight, comprising:
- a rear cut out section disposed along a central portion of the firing pin;
- a forward cut out section for receiving the extractor disposed proximate a forward end of the firing pin, wherein the cut out section comprises:
- a notch configured to engage the extractor and disposed along a forward portion of the cut out section forming a substantially perpendicular surface relative to a longitudinal axis of the firing pin;
- and
- an angled end surface disposed along a rear portion of the cut out section;
- and
- a relief cut extending at least part way between the forward cut out section and the rear cut out section and engaging the first flat section at a ninety-degree angle.
