13 Round Mosquito High Capacity Magazine Basepad

Alternative Views:

The +3 (Plus 3) aluminum basepad replaces the factory plastic basepad on your Sig Sauer Mosquito 22lr pistol magazine to allow for three (3) additional rounds to be fit into the magazine. This turns your factory 10 round magazine into a 13 round magazine and 1 in the chamber for a total of 14 rounds in the gun. The +3 basepad is also longer than the factory plastic basepad and allows for more positive seating of the magazine in the gun. Additionally the aluminum construction is more durable than factory plastic basepads making your magazine less prone to breakage upon dropping.

* Please note that when using the Shockbottle basepad to increase the guns magazine capacity, you will loose the slide lock to open on the last shot fired (the slide will not lock back on an empty mag upon firing the last shot).

2 of 5 Slider stop removal March 22, 2022
Reviewer: Steve Holding from Spokane, WA United States  
The instructions said I need to remove the slider stop in order to get the extra bullets to take.  I could not see how to do that  without breaking it.  Any suggestions ?
