Extended basepads for the FNS9 and FNS40 striker fired pistols from FN. These Gen3 pads (as of April 5, 2016), designed and produced by Carbon Arms, add 6 rounds to the 9mm and 5 rounds to the .40 S&W magazines. Slight tuning or trimming of the magazine follower (uses factory folloer) may be beneficial. They are anodized CNC machined billet aluminum and boast tool-less disassembly that is simple and durable. Fits the USPSA Limited gauge. ISMI spring is recomended for 9mm.
We have tested these basepads extensively for over a year, as have several members of Team FNH during 3Gun matches.
