STI/SV Base Pad 4G2 Blue
The TTI Base Pad for STI, SV, SPS, & Rescomp Magazine Tubes
Use the TTI Base Pad with the TTI spring and TTI Follower for maximum capacity.
This Patented push pin design is indestructible and will not come off until you are ready to remove it. One Piece construction made from solid aluminum, will not break or come loose, which is essential in the heat of competition.
This base pad allows the magazine to be disassembled in seconds with one hand and no tools. You don't have to worry about losing small parts or specialty tools to disassemble it. Feel free to drop mags equipped with this base pad in any shooting environment. They don't crack when dropped on concrete or rocks and they don't have moving parts to get jammed up with dirt and debris.
It's simple, the TTI Pad doesn't crack, it's easy to get on and off the mag, and it gets the highest capacity possible. It's the last base pad you will ever buy.
The new TTI base pads have been redesigned with a wider notch to fit onto all the magazines without having to grind down the tube's bottom lips like in the past.

*4G2 (4 the Gauge) is recommended for anyone doing mag tuning who has a USPSA mag gauge. The 4G is angled in the back and will fit the gauge while allowing one extra round over the 3mm. It's the base pad that all the mag tuners have been waiting for to get that extra edge!
7G for 140mm Open mags and 126mm Open or Limited mags, or older under length Infinity Big Sticks
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 awkward to do fast reloads.
7G for SPS 134/164mm 38/9mm and 40S&W
- 30rds in 164mm 38/9mm
- 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.
