Ultralight Short +6 Base Pad For New Sig Sauer MPX 35 Round "THRiL" 9mm Magazines

The SIG SAUER enhanced factory MPX 35 round magazine is a substantial improvement over the previous factory mags. In addition to 5 extra rounds, these new magazines have increased reliability and durability in a lightweight polymer body. 35 rounds just isn’t enough. Those are rookie numbers, and we’re here to help you kick those numbers up! Maybe you don't want to add a whole 9 rounds, how about 6? We’re pretty happy with 41 rounds and we know you will be too. Using our patented, proven push-pin design, no tools are necessary for field strip cleaning. The one piece design of the base pad adds just enough weight (2.1oz) to help empty magazines drop free and clear. The shape of our base pad is designed to save weight, and make it easy to grab when you’re going for a fast and consistent reload. Machined out of billet aluminum and hard anodized, we set your durability and longevity concerns to rest. All machining and manufacturing is done in the USA.

    Don’t want to use my Thril mags without this extension!

  • work great, look great

    I typically only use these as +5, not the full +6 because I like the nice even 40-round capacity, but they've worked flawlessly and (in my opinion) make the mags look better as well. the one note I'd have for anyone looking to purchase one is to make sure to remove the plastic piece that locks the OEM baseplate in place. I skipped that the first time and found out the hard way that this makes them not fit +5 rounds and nearly impossible to remove. after fighting for a while to get it off (brute force was the answer) I removed that plastic piece and it's been clean sailing ever since. I ended up getting 4 of them to cover all of my MPX mags.

  • Great product and great customer service!

    I ordered 3 of these for my Sig MPX and they're awesome! My original order appeared to get lost in the mail and when I called about it, they immediately got a new order shipped out to me right away. I give the product and the customer service 5 stars!!!
