0. 22. The firearm of claim 19, wherein the optical sight defines a sight axis and wherein the recess is sized so as to lower the sight axis to a height that corresponds to the height of a non-optical sight for the firearm.
0. 23. The firearm of claim 22, wherein the recess lowers the sight axis by approximately 2 mils.

This application FIG. 4A is a detailed perspective view of the slide housing of FIG. 4.having outer walls that are hollow and are threaded and can receive fasteners to secure the plate 212 into the recess (see, e.g., FIG. 4A). Alternatively, the mounting components 204 can be screw holes that receive screws or other fasteners to secure the plate 212 into the recess. Alternatively, the mounting components 204 can be projections that fit through the holes 214 of the plate 212 so that the plate 212 is secured in the recess 205 via friction.

Regardless of how the mounting plate 212 is secured within the recess 205, the mounting plate 212, when positioned within the recess 205, is maintained in a fixed relationship with the front sight 122 and also with respect to the axis of the barrel 132. Thus, the mounting plate 212 can be positioned within the recess 205 and secured thereto. The fixed sight 220 can then be moved laterally across the groove 216 until it is properly aligned with the front sight 122 so that the pistol 100 is sighted in. Due to the fixed arrangement of the plate 212 with respect to the axis of the barrel 132, the plate 212 can be removed and re-installed into the recess 205 and the sighting orientation of the fixed sight 220 with respect to the front sight 122 can be maintained. Thus, the sight can be switched out without requiring the shooter to re-sight the firearm.

Further, as shown in FIG. 6B, an optical sight 230 such as a Trijicon RMR, a Leupold Delta Point, an Insight MRDS, etc. can also have a mounting plate 232 that is sized to fit within the recess 205 and has openings with inner walls that engage with the mounting components 204 in the same manner as the mounting plate 212 described above. Thus, the recess 205 and the mounting components 204 allow for the interchangeability between multiple different sights without requiring that the sights be re-sighted to the pistol when switched back and forth.

A further advantage of the recess 205 is that with a typical optical sight 230, the height of the center of the optical sight 230 is reduced by an amount of the recess. In one implementation, the recess is 2 mils deep which results in the center point of a standard optical sight 230 being in line with the visual line of a standard fixed set of iron sights. Consequently, the sight picture of the shooter using an optical sight and an iron sight can be maintained to be closer to each other. This further allows the shooter to hold the pistol with respect to their eyes at about the same orientation regardless of which sight is being used which enhances the shooter's accuracy.

While the foregoing has shown, illustrated and described various embodiments and implementations of the present invention, it will be apparent from the foregoing description that various changes and modifications to the apparatuses described above and the uses thereof may be made by those skilled in the art without departing from the scope of the present invention. Hence, the scope of the present invention should not be limited to the foregoing discussion but should be defined by the appended claims.
