On Orders Of $200
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.

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.

The fit to the magazine: the machining and the finish were prefect.
MPX +11 base plate

As always a great product. It is a bit heavy, but solid craftsmanship. The extra weight also helps the mag drop as well. I've used these base plates on several Glock mags and this company never disappoints. To be honest the first time I loaded a stock magazine I was looking at it like "how come there is so much unused space? Why couldn't the mag be shorter?" This magazine plate and spring makes sense, looks great and gives a higher capacity.
So far so good.

Install was a breeze, loads 41 rounds in my magazine with the gen 1 mags. Works okay so far.

This TTI base pad looks a lot bigger in person that on your website. I don't know if I like that. I'm sure it will function just fine. I was going for weight over round capacity and it does suit me there!

Works great and very high quality . I would recommend this product to my friends.
Factory magazine spring insert

I'm order to meet the objective of the +11 base pad, do you remove the spring guide or trim it to a certain length? Seems some of it should remain to prevent spring bind when fully loaded.
Other than that question, the base plate is a rock solid piece of MPX goodness!

After my plus 10 mag extension mysteriously disappeared at a match, I pick up the plus 11 works great love TTI products. Wish they would make a plus zero base pad for the MPX mags.

I've used similar base pads on my flock Pistol mags. I've found the MPX base pads to be exactly as advertised.
