TTI Base Pad for STI/SV Magazines 7mm - Titanium Gray

The 7mm is our longest extension for the Staccato/Infinity/Springfield Prodigy/Atlas/Infinity/MBX 9/38 2011 style magazine and Bul Armory SAS II Pistols.

Although it will work with all 2011 style magazines it is recommended for the 140mm Magazines for Open/Unlimited division and the 126mm because that’s what John Wick will do. On the 140mm magazine, the 7mm extension bumps the capacity from 20 rounds to 22 rounds with the factory spring and follower. For even more added capacity, use our thin competition follower and extra power 11 coil spring for an impressive 24 round capacity (but will not lock the slide to the rear on the last round fired).

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.

NOTE

*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.*
