On Orders Of $200
Not for sale to California residents. A courtesy email will be sent to CA residenta 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 residenta 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.

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 10 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.

The fit and finish of the +10 base plates is perfect. I had no issues with installation. In addition to the extra capacity, I can't help but think that the aluminum base plate would add some extra durability to the mag should you drop it. I highly recommend this product

I purchased the black 10 round magazine extension. Simple and easy install, extra power spring included to make up for the difference in length, fit and finish is perfect, and shipping was fast. I prefer Taran mag extensions over others I've purchased. I've already ordered more. If you want and/or need 10 more rounds for your MPX mag then you can't go wrong with Taran Tactical.
The Best Sig Sauer MPX Mag Extension You Can Buy

I bought another companies' MPX extension because I thought it was less expensive, but that company made you paid extra for the spring, so it ended up costing more. Taran's are less expensive and a better design. Stay with Taran Tactical. He makes the best.
