Abstract

Cocking tab inserts and breechblock slides and firearms including the same are disclosed. An example apparatus includes a breechblock slide; a cocking tab insert removably coupled to the breechblock slide; and a sight removably coupled to the breechblock slide and overlaying the cocking tab insert to substantially prevent the cocking tab insert from being inadvertently removed from the breechblock slide.

Claims

1. A firearm, comprising:

a breechblock slide;

a cocking tab insert removably coupled to the breechblock slide; and

a sight removably coupled directly to the breechblock slide and overlaying the cocking tab insert to prevent the cocking tab insert from being removed from the breechblock slide.

2. The firearm of claim 1, wherein the cocking tab insert is a first cocking tab insert, further including a second cocking tab insert removably coupled to the breechblock slide, the first cocking tab insert coupled on an opposite side of the breechblock slide as the second cocking tab insert.

3. The firearm of claim 2, wherein the first cocking tab insert is offset relative to the second cocking tab insert along a longitudinal axis of the breechblock slide.

4. The firearm of claim 2, wherein the first cocking tab insert is a first size and the second cocking tab insert is a second size, the first size different than the second size.

5. The firearm of claim 2, further including a third cocking tab insert, the third cocking tab insert to be coupled to the breechblock slide when the first cocking tab insert is removed from the breechblock slide.

6. The firearm of claim 1, wherein the breechblock slide defines a groove that receives and houses the cocking tab insert.

7. The firearm of claim 6, wherein the groove is a dovetail groove.

8. The firearm of claim 6, wherein the groove is a first groove, further including a second groove defined by the breechblock slide, the second groove to receive the sight to removably couple the sight to the breechblock slide.

9. The firearm of claim 8, wherein the second groove is a dovetail groove, further including a notch defined by the sight between a first portion of the sight and a second portion of the sight, the first portion to be received within the dovetail groove to couple the sight to the breechblock slide, the second portion to overlay the cocking tab insert.

10. The firearm of claim 1, wherein the cocking tab insert is to be coupled to the breechblock slide in tension to couple the cocking tab insert and the breechblock slide.

11. The firearm of claim 1, wherein the cocking tab insert defines an inner channel to enable the cocking tab insert to be placed in tension when being coupled to the breechblock slide.

12. The firearm of claim 1, wherein the cocking tab insert is to extend from an exterior surface of the breechblock slide to provide a gripping surface.

13. An apparatus, comprising:

a breechblock slide;

a loading aid removably coupled to the breechblock slide; and

a sight removably coupled directly to the breechblock slide and overlaying the loading aid to prevent the loading aid from being removed from the breechblock slide, the loading aid to extend from an exterior surface of the breechblock slide to provide a gripping surface.

14. The apparatus of claim 13, wherein the breechblock slide defines a recess to receive the loading aid within the breechblock slide, the recess and the loading aid being complementarily sized.

15. The apparatus of claim 14, wherein the recess includes a first portion and a second portion, the first portion intersecting the second portion, the second portion being disposed on a lateral side of the breechblock slide.

16. The apparatus of claim 14, wherein the recess is transverse to a longitudinal axis of the breechblock slide.

17. The apparatus of claim 14, wherein the recess includes a dovetail groove to receive the loading aid.

18. The apparatus of claim 14, wherein the recess is a first recess defined on a first side of the breechblock slide, further including a second recess defined on a second side of the breechblock slide, the first side opposite the second side.

19. The apparatus of claim 18, wherein the first recess is offset relative to the second recess along a longitudinal axis of the breechblock slide.

20. The apparatus of claim 18, wherein the first recess is a mirror image of the second recess.

21. The apparatus of claim 14, wherein the recess is defined adjacent a rear of the breechblock slide.

22. The apparatus of claim 13, wherein the loading aid is a first loading aid, further including a second loading aid removably housed within the breechblock slide, the first loading aid opposite the second loading aid.

23. The apparatus of claim 13, wherein the loading aid includes an L-shaped profile and an outer surface including a projection to enable gripping.

24. The apparatus of claim 13, wherein the loading aid comprises:

a first leg;

a second leg coupled to the first leg, the first and second legs including an L-shaped cross-section, the first leg to be received in a first groove portion defined on a lateral side of the breechblock slide, the second leg to be received in a second groove portion defined by the breechblock slide, the first groove portion to intersect the second groove portion, when the first and second legs are received in the respective first and second groove portions, an outer surface of the first leg to extend from an exterior surface of the breechblock slide to provide a gripping surface, when the first and second legs are received in the respective first and second groove portions, the sight is to overlay the second leg to couple the loading aid to the breechblock slide.
