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.
with Grams Spring & Follower kit:
9x19 = 24+1 (+5 rounds)
40S&W = 20+1 (+4 rounds)
To be used with your stock magazine tube, not included...
NOT to be used with Compact frame models.
Note: The design of the Gram Spring & Follower allows for maximum capacity. For this reason, your slide will NOT lock back when you run the gun "dry". If you want the slide to lock back when empty, you will need to use your stock follower. See above for capacity based on spring/follower options.
*Based on our testing. Actual capacity may vary, depending on factors such as spring age, use of loader, other.
