Abstract

To allow a reflex sight to be mounted to the slider of a handgun and removed without the need for tools, an adapter shoe may be secured to the slider to provide an interface between an optics-ready recess of the slider and a mounting element that forms part of the reflex sight assembly. The adapter shoe may provide a dovetail track that engages complementary dovetail features of the mounting element. A push button retention mechanism may be biased to lock the mounting element within the adapter shoe. Actuation of the push buttons may retract the retention mechanism and allow the reflex sight assembly to slide out of the dovetail track.

Claims (30)

1 . A reflex sighting system removably mountable to a slider of a handgun, the reflex sight comprising:

(A) a lens;

(B) a light source;

(D) electronics for controlling the operation of the light source; and

(E) a housing that houses one or more of the battery and the electronics;

(F) a mounting element that is configured to mount the reflex sight to the slider, the mounting element comprising:

(a) a sight mounting component comprising:

(i) a sight mounting surface on which the reflex sight may be mounted and secured; and

(ii) a first complementary lateral dovetail engagement feature;

(b) an adapter shoe comprising:

(i) a first mounting portion for mounting the adapter shoe to the slider; and

(ii) a second mounting portion comprising a second complementary lateral dovetail engagement feature that is complementary to the first complementary lateral dovetail engagement feature;

wherein the first complementary lateral dovetail engagement feature and the second complementary lateral dovetail engagement feature each comprise a dovetail profile and wherein the sight mounting portion is configured to slide laterally along a dovetail track provided by the adapter shoe.

2 . The reflex sighting system of claim 1 wherein the first mounting portion comprises an outer mounting element configured to be mounted into a recess of the slider.

3 . The reflex sighting system of claim 1 comprising one or more fasteners for securing the adapter shoe to the slider.

4 . The reflex sighting system of claim 1 comprising a retention mechanism for retaining the sight mounting component to the adapter shoe.

5 . The reflex sighting system of claim 4 wherein the retention mechanism can be operated without tools to cause removal of the sight mounting component from the adapter shoe.

6 . The reflex sighting system of claim 4 wherein the retention mechanism comprises one or more hand operated actuators that, when actuated, allow the sight mounting component to be released from the adapter shoe.

7 . The reflex sighting system of claim 4 wherein the adapter shoe comprises a notch that engages the retention mechanism.

8 . The reflex sighting system of claim 1 wherein the first mounting portion is configured to be mounted within a recess of the slider.

9 . A method for mounting a reflex sight to a handgun comprising:

(A) securing an adapter shoe to a slider of the handgun, the adapter shoe comprising:

(a) a first mounting portion for mounting the adapter shoe to the slider; and

(b) a second mounting portion comprising a first complementary engagement feature;

(B) moving a reflex sight assembly comprising the reflex sight into engagement with the adapter shoe, the moving comprising engaging the first complementary engagement feature with a second complementary engagement feature of the reflex sight assembly that is complementary to the first complementary engagement feature;

wherein the first complementary engagement feature and the second complementary engagement feature each comprise a dovetail profile and wherein the moving comprises sliding the reflex sight assembly laterally along a dovetail track provided by the adapter shoe.

10 . The method of claim 9 comprising securing the adapter shoe into a recess of the slider with one or more fasteners.

11 . The method of claim 9 comprising retaining the reflex sight assembly to the adapter shoe with a retention mechanism that is actuatable without tools to disengage the retention mechanism from the adapter shoe to allow the reflex sight assembly to be removed from the adapter shoe while the adapter shoe is secured to the slider.

12 . The method of claim 9 wherein the reflex sight assembly comprises a reflex sight and a mounting element comprising the second complementary engagement feature, the method comprising securing the reflex sight to the mounting element with one or more fasteners.
