Base Pad For Sig Sauer P320 9/40 Magazine


Always Enjoy Free Shipping On Orders Of $200

Product Description

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 residence 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.

The pin set screws are set with Loctite® at the specific tension we recommend, and will generally never need an adjustment. Tightening the base pad screw is not recommended and may be difficult because the screw is set with Loctite®; trying to force the set screw to turn could result in stripping the screw. We do not warranty base pads for stripped heads on set screws or pins lost in result of tampering with the set screw.

*Remove the metal insert at the bottom before installation*

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 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 onto the magazine 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.

  1. P320 c

    Posted by on Sep 6th 2019

    Properly mounted not loose thanks highly recommended

  2. Great product for P320 Full X5!

    Posted by Unknown on Aug 20th 2019

    I bought 2 extension to convert my original p320 mag to fit my new X5 grip! It works great and very easy to install

  3. Works great with the Sig P320 X-Compact

    Posted by Richard Armstrong on Aug 10th 2019

    Attaches perfectly to the 15 round mags that the X-Compact comes with. They are a pain in the bum to get on, but with a bit of frustration you'll get there. Lol. But well worth the effort.

  4. Outstanding

    Posted by Tom T. on Jul 22nd 2019

    I have TTI mag extensions for several of my guns, including, Glock, SIG and M&P. All have performed flawlessly. I recommend TTI mag extensions to anyone looking to add some rounds to their mags. Additionally, I have purchased mag extensions from other companies that have been a disappointment. I will only but TTI products. Keep up the great work TTI.

  5. Buy It!

    Posted by Sal on Jul 18th 2019

    Holy smokes!!! These are amazing. Excellent quality, easy to install... just awesome!

  6. X5 26 rounds

    Posted by Unknown on Jul 16th 2019

    Got these for my 320x5 21 rd mags put 26 rds in them , run like a champ just like all the rest of my TTI base pads.

  7. Looks great and easy to install

    Posted by Christian Barrett on Jun 8th 2019

    This extension was very easy to install and functions great. I really like the weight added to the stock magazine.

  8. Just buy these

    Posted by Christian K on Jun 5th 2019

    I was impressed on not only the craftsmanship but the engineering around the ease of installation. Takes about 5x more time to remove the factory base pad than to install these amazing upgrades. Will be buying more for sure.

  9. Works with p320 x5

    Posted by Unknown on Dec 3rd 2018

    Works well with the x5 mag well and 17 round mags

  10. Always Quality

    Posted by Bob on Nov 7th 2018

    The +5 Sig base pads are exactly as expected. Easy on and off but still lock on.
