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.

· 24rds in SV/STI 140mm 38/9mm

*This is preferred base pad for non-big stick tubes in Open division to get 23-24rds without extending the mag too long where it’s tricky to do fast reloads.

· 23rds in 134mm 38/9mm.

· 21rds in 134mm 40S&W

*Due to the variances in mag tube dimensions from different companies and even different generations of mags from the same company, the base pad may require minor fitting to the tube and the back of the lips may need the sharp edges buffed down so the mag will fit the gauge.*

    Base pad

    Posted by Mark on Sep 17th 2021

    Solid overall. Has some wiggle to it one attached, otherwise would be 5 star. The 4mm pad doesn't fit in the 17 rd 2011 mags, but the 7 mm does due to a design difference on the edges. Does look great on though!

    Not what I thought

    Posted by Christian Cervantes on Mar 22nd 2021

    I put on the Taran base place for my staccato C2 duo and my staccato xc and the base plates were to thin so the metal mag shows at the bottom before you see the base plate. Not what I was looking for. But functionally it worked fine. I just wish the base plates were thicker. TTI Rep: The gap between the basepad and the pistol that shows the magazine a little is intentional. That gap is there to ensure that the magazine locks into place when reloading. We have noticed that when we make the basepad fit just perfectly it will cause issues with the magazine not locking in on reloads. In regards to the thickness of the basepad, that is to ensure it is legal for competition. I hope this explanation helped. LT

    TTI 4 mm Basepads

    Posted by Larry Francis on Jan 18th 2020

    I was replacing my old Basepads because I switched Magwells to one that requires the low profiles. I struggled with my old pads when I got them trying to get 20 rounds in them even with my Grams followers. I ended up modifying them to make them fit 20 and be reloadable. Straight outta the box I can easily fit 20 with the TTI. Never going back.
