This items uses the Grams Follower & Spring Kit...  

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.

Below installation video shows the use of the optional Grams Spring & Follower kit.

Got 6 - 20 Rounds No Problemo

- 02nd July 2014

I shoot USPSA on the weekends and I bought three, then another three, for Limited. While I am not very good, these extension and the Pistolgear magwell are very good. Installation was simple and capacity is excellent. The more rounds in the magazine, the fewer reloads required.

Ordered 2 140mm mag extensions for my XDM 9mm on saturday and got them on thursday, I installed them both on my mag tubes in about 2 minutes, the fit/finish and quality of bases is awesome, I loaded up both and went outside and emptied them both a few times without a single issue. Ordering was simple, shipping was fast, the price is good and products are very well built with great function, pistolgear has my biz for all my XDM needs for life!

140mm extension

- 12th August 2011

I used the original follower and only got 19 rounds in. I guess if you use the included follower it will take more. The follower included doesn't seem quite as good as the original.

Excellant Drop in Product!!

- 02nd October 2010

I have nothing but praise for this add on base pad. This is by far the easiest way to go high cap for a limited gun. A true drop in part. The grams follower and spring worked first time right out of the box. No tuning or spending extra $. Thanks to the Pistolgear team.
