Patriot Defense | Tanfoglio Base Pad - Extended

Patriot Defense | Tanfoglio Base Pad - Extended 

 NOTE: OUR K9 option is the newest option available. These have been designed specifically for use with the 9mm K9 (Large Frame) tubes from Mec-gar. We've redesigned the internal pocket to allow a smoother transition into the magazine tube. Many base pads are oversized and one size fits all for magazine tube calibers. This allows variations in the Tanfoglio magazine tubes that allow followers to roll or get hung up on spacer lips.

The Patriot Defense precision CNC 140mm base pads are made from American brass square stock. These feature a unique captured dog fastener that's adjusted in or out from the bottom utilizing a provided 1/16" HEX wrench. When utilized with the grams engineering spring and follower they can achieve up too +6 capacity in 9mm. These will fit the USPSA mag gauge for 140mm magazines with the factory supplied 17rnd mec-gar magazines.
