Adds 11 Rounds to your magazine with adding minimal weight!!

Not for sale to California residents. A courtesy email will be sent to CA residents who place an order for a base pad that has the capability of taking a magazine past ten rounds. Ultimately a refund will be issued. CA residents can only purchase +0 base pads or GLOCK 43 and GLOCK 42 base pads. The 43 and 42 base pads do not take the mag capacity past ten rounds.

Installation Tip: Remove the stock MPX base plate and floor plate from the magazine so that only the spring and follower should be left. Slide the base pad onto the magazine and then finish pressing it into place abruptly and firmly. Easing the base pad onto the magazine may result in the spring not dropping fully into the pocket in the base pad.

TTI Firepower Sig MPX Carbine Magazine Extension:
- Designed to work with the STOCK Magazine spring.

- Overall weight 2.4 oz.

- Length, 2 inchs.

- Patented, proven push-pin design.

- No tools needed, just push the pin down, slide the base pad onto the magazine and push the pin up to lock the base pad onto the magazine. Easily attaches and detaches from the magazine.

- No specialty tools, devices, or additional springs required for assembly/disassembly, simply pop off the basepad and remove the insert at the bottom of the spring and slide on the extension.

- One piece design; no small parts to keep track of.

- Minimal length addition to allow usage while in a prone position.

- Holds 41+1 in 9mm.

- The added weight helps the magazine drop free easier for faster reloads.

- CNC machined from billet aluminum.

- Hard anodized.

- Made in the USA.

This Taran Tactical Innovations Sig MPX Carbine base pad works on the Sig MPX stock 30 round 9mm magazine. This TTI base pad will add 11 extra rounds to your stock Sig MPX Carbine 30 round magazine. This TTI base pad does add a little extra weight to the magazine which helps the empty mag drop free easier for faster reloads. This TTI Sig MPX base pad, just like all of our base pads, is designed to give you the edge over your adversaries. We use our patented push pin design to lock the base pad to the magazine, which makes for easy field stripping and cleaning your magazines between stages. Just push down the pin, slide the base pad on and push the pin up to lock the base pad onto the magazine. Our one piece design is great because there are no extra parts or tools needed to attach the base pad to your magazine. The base pad itself is machined out of billet aluminum and is hard anodized to ensure durable long lasting color. All machining and manufacturing is done in the USA.

    Good product

    Very easy to install and do add some weight to help the mags drop free. Mag won’t seat with a full 41 loaded and 1 in the chamber.

    Sig Mag extension +11

    Posted by Duane Jefferson on Nov 29th 2021

    One of the best things I got for my MPX K. Works well & flawlessly. Took me a minute to realize that you have to take lock plate out & only keep the follower. I only gave 4 stars because it only holds 40 instead of 41 like it says. Besides that, perfect! I’d recommend!

    Very nice update

    Posted by Bart Clarkson on Nov 19th 2021

    I have both the ultralite and more blocky mag extensions, and these are nicer. While I get the argument that the added weight of the non-ultralite is kind of a feature in terms of helping pull the empty magazine down on ejection (empty it’s a bit sticky, just is), inasmuch as dropping these expensive magazines into the dirt isn’t something I’m interested in, I don’t care. I grab. So beyond that only a few things matter. Number one they’re dead right on getting the expected number of rounds down. The included spring is on the money. Installation is easy, and easily reversible for whatever reason you might have. Last but not least, hey, they do look cool. I’m not into the John Wick red color myself, but it’s your gun, rock out.

    MPX Mag extension

    Posted by Lyle Johnson on Sep 17th 2021

    Well, my extensive testing....150 rounds (ammo is expensive) ran flawlessly. Just loaded the mag, and emptied the mag, dropped the mag and dusted it off. Taran tactical carries good stuff. You can't go wrong.
