Product Description

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.

Using the table below, you will be able to identify what parts you will need for your given pistol depending on what division you want to shoot.

To use this Table: First, look for what division in which you want to shoot. Second, find the the Tube Length. Third, locate what caliber are you shooting. Once you have found all of identified what parts you are using, you will then be able to see which basepad, spring and follower you will need. You will also be able to tell what capacity you achieve with the given configuration.

  1. TTI 4mm Basepads for SVI

    Posted by Jasmine on Jul 27th 2017

    First and foremost, the TTI 4mm basepads on an SVI 140mm tube fit the magazine gauge keeping me from getting bumped to Open Class in USPSA....bonus. Second, with the TTI follower and spring I can get 1 extra round in the magazine. And finally, it's insanely easy to slide off the basepad and clean the mag between stages.

  2. Why would you even look at other base pads!?

    Posted by Unknown on Jul 17th 2017

    Absolute best fit, best ability to function, and the EASIEST to maintain! I ordered 2 just to try out and needless to say ordered 3 after my first range day with them! I love these base pads and will be converting all of my carry optic mags to tti pads as well.

    With my .40 sti 140mm mags and grams followers I get 20rnds reloadable in every mag I own. No rattle, easy to reload, PERFECT!

  3. Outstanding Basepads!!!

    Posted by David R White on Apr 16th 2017

    I have been using TTI Glock Basepads for a long time and when I decided to graduate up to an STI there was no question on what Basepads I was going to choose for my mags. The Basepads are machined so well I would say they are indestructible and shoot on concrete a lot so my mags take a beating. Read the product description carefully as you will need their followers as well to obtain max capacity.

  4. This base pad is the easiest and simplest to use

    Posted by Bob Wright on Mar 13th 2017

    I have been a USPSA competitor since 1992.Over the years I have tried just about every base pad that came on the market.This product is the simplest to use. It requires no tools and very little effort to take it on and off your magazines.I have been replacing all of my base pads a few at a time on all my limited and open guns.I think it is the best design on the market and I highly recommend them.

  5. Perfect performance; simple install.

    Posted by DJL on Jul 4th 2016

    Bought the STI/SV base pads for 140mm STI 40 cal mags, using the stock springs. The installation was effortless, gained two additional rounds per mag, and they function beatifully. They look great too.
