Adds 6 Rounds to your magazine!

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.

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

- Holds 36+1 in 9mm.

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.

    So per usual TTI makes great products. That being said I can never seem to get the advertised number of additional rounds into my mags it has been this way with numerous mag extensions I’ve bought. There is also a way to achieve this number of rounds by cutting the MPX limiter in the mag. This all being said just buy the +11 and save yourself time

    I got this for USPSA and it works great. Adds virtually no length to a 30 round mag and you get 6 extra rounds and a durable baseplate. Highly recommend it and I may put one on all my standard 30 round mags.
