Gun sights are used to help improve accuracy and there are many different types of sights available to choose from. A common type of gun sight that typically comes standard on handguns is an iron sight which consists of a forward component and a rear component that in combination help a user direct the projectile towards a target. While very common, iron sights, may not always be the preferred type of sight for a given firearm. For example, a telescopic sight may be more useful for long range targets when using a rifle. Laser sights and reflex based optical sights may be used in place of an iron sight on a handgun to provide the user with a more highly visible sight.
It is not always possible to simply replace an iron sight with a different type of sight. For example, certain types of optical sights are manufactured with a standard profile that can be connected to the top of a firearm. This standard profile, however, may not fit every type of firearm. For example, some handguns manufactured prior to the broad use of optical sights may have a profile that cannot be easily adapted to mount an optical sight due to the narrowness or roundness of an uppermost surface of the slide mechanism of the firearm. Adapters for the slide mechanism have attempted to allow optical sights to be used with these types of firearms but suffer from various drawbacks such as not being sufficiently strong enough to endure the recoil forces on the slide mechanism when the firearm is fired.
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 more complete understanding of the present technology may be derived by referring to the detailed description and claims when considered in connection with the following illustrative figures. In the following figures, like reference numbers refer to similar elements and steps throughout the figures.
Elements and steps in the figures are illustrated for simplicity and clarity and have not necessarily been rendered according to any particular sequence. For example, steps that may be performed concurrently or in a different order are illustrated in the figures to help to improve understanding of embodiments of the present technology.
The present technology may be described in terms of functional block components and various processing steps. Such functional blocks may be realized by any number of components configured to perform the specified functions and achieve the various results. For example, the present technology may employ various materials, finishes, dimensions, and geometries, which may carry out a variety of operations suited to a specified application or environment. In addition, the present technology may be practiced in conjunction with any number of systems configured for operation with firearms, and the system described is merely one exemplary application for the technology. Further, the present technology may employ any number of conventional techniques for machining, metalworking, and gunsmithing.
Methods and apparatus for an optical adapter for a firearm slide according to various aspects of the present technology may operate in conjunction with any type of handgun or various slide mechanisms used in firearms. Various representative implementations of the present technology may be applied to retrofitting an existing semi-automatic handgun, modifying a new firearm, or manufacturing a new firearm. For example, the described technology may be used to replace or modify an original factory installed slide mechanism and one or more internal components of a Beretta® model 92 pistol, and other like models such as: the Taurus® PT92, Girsan® Regard MC, Helwan 920, Vektor Z88, SP1, and SP2, Yavuz 16, and the AT92, to provide a suitable surface for mounting an optical sight on the pistol when the slide mechanism as originally manufactured is not suitable for receiving a mounted optical sight.

The recessed the flat upper surface 202 may be formed by modifying an existing stock slide mechanism. For example, an upper surface of a factory manufactured stock slide mechanism may be machined to form the recessed the flat upper surface 202. This modified slide mechanism may then be used in place of the original stock slide mechanism. Alternatively, the flat upper surface 202 may be formed as part of a replacement slide mechanism that was manufactured as a direct replacement for a stock slide mechanism.
Whether by modifying a stock slide mechanism or replacing a stock slide mechanism with a replacement, the flat upper surface 202 may expose interior components of the slide mechanism or render existing stock internal components nonfunctional. For example, if the prior art unmodified slide mechanism 100 is modified according to the present technology, the recessed flat upper surface 202 may extend downwards into the upper surface of the unmodified slide mechanism 100 such that a first opening 212 for a standard firing pin block 110 (See

The adapter plate 402 may comprise a substantially flat top surface 702 and an underside surface 704 that may at least partially conform to the top surface of the slide mechanism 200. Alternatively, the underside surface 704 may be flat and configured to mate up against the flat upper surface 202 of the modified slide mechanism 200. A second set of mounting holes 406 may be positioned on the adapter plate 402 to allow the adapter plate 402 to be coupled to the mating first set of mounting holes 206 on the flat upper surface 202 of the slide mechanism 200. Any suitable type of fastener such as a screw or bolt may be used to couple the adapter mounting holes 406, 206 together.
The adapter plate 402 may further comprise one or more mounting busses 410 disposed along the top surface 702 that are configured to couple to a pair of mating bosses in the optics assembly 500. A third set of mounting holes or receiving ports 412 may also be located on the top surface 702 and may be used to couple the adapter plate 402 to the optics assembly 500. A sighting element 404 may be positioned along a rearmost edge of the adapter plate 402. A forward section of the adapter plate 402 may comprise a lip 408 configured to be positioned along the top most surface 218 of the slide mechanism 200 when an angled forward edge 414 is positioned in the forward end 210 of the flat upper surface 202.

In one embodiment, the modified firing pin block 1200 may comprise a body having a central body having a pair of opposing ends. Each of the opposing ends may comprise an edge section 1202, 1204 that extends perpendicularly away from the ends of the central body. A center catch 1208 may extend perpendicularly away from a center portion 1206 of the central body in a direction opposite that of the edge sections 1202, 1204. The center catch 1208 may comprise a lip 1210 and is angled perpendicular to the direction of the center catch 1208 and is parallel to the central body. A recessed detent 1302 may be disposed in a surface of the center catch 1208 that is opposite that of the lip 1210.
To accommodate the modified firing pin block 1200, the firing pin may also need to be modified. For example, referring now to
The modified firing pin 1700 may further comprise a relief cut 1704 that may extend from a section proximate and end of the modified firing pin 1700 to the second cut out 1604. The relief cut 1704 may provide an improved fit when positioned within the modified slide mechanism 200.
