  1. Slide locks back. Finally!

    Posted by on Oct 14th 2019

    After trying two other spring companies, my slide finally locks back when I empty my magazine. Great springs for building a speed gun.

  2. M&P springs

    These are the best springs I’ve found for 140mm M&P magazines

  3. Superb Products!

    I ordered this pin and set screw set as well as a spare spring for all of my Glock and S&W M&P 2.0 BASE PADS. For the minimal cost, I recommend everyone do the same just to have in your armorers tool box.

  4. Awesome

    I uses use these in my hk vp9 mags with +5 mag extensions from hkparts and they last thousands of rounds still locking the slide back.

  5. Unequaled

    My springs needed replacing, ordered Brownell's springs, then could only load 19rds. Replaced with the correct springs from TTI, 22-23 rds. Don't settle for others, use TTI springs with your TTI basepads.
