Blueline Magazine Extension for S&W M&P

Blueline Magazine Extension +3 

Smith & Wesson M&P 9/40 


Designed in collaboration with a current SWAT Operator and US Army Veteran, our Magazine Extensions offer:            


Confident magazine indexing through our patent pending design. 

Improved grip support for shooters with larger hands. 

Basepad allows for an effortless strip with the knife-edge of the support hand on malfunctions or stuck magazines. 

Designed by a door-kicker, for door-kickers. 


The kit comes with the magazine extension only, through extensive testing we have found a longer spring unnecessary.
