This kit uses your XD(m)'s stock follower...
PistolGear is proud to offer its 140mm magazine extension, designed by gamers for gamers. Made of aluminum and with a removal backplate, this rugged design allows you to remove or install the extension in seconds. Unlike other magazine extension on the market, you will not need to fight with this one and it will NEVER come off of your mag tube during a reload or when the magazine hits the ground.
MAX* capacity with included spring & stock follower:
9x19 = 22+1 (+3 rounds)
40S&W = 18+1 (+2 rounds)
To be used with your stock magazine tube, not included...
NOT to be used with Compact frame models.
*Based on our testing. Actual capacity may vary, depending on factors such as spring age, use of loader, other.
When using your stock follower, you may need to modify the bottom of the follower so it does not make contact with the extension. Please see the below image for some illustrative instruction.
Below installation video shows the use of the optional Grams Spring & Follower kit.
