Magazine base pad for STI 2011 factory magazine, Gen1 and Gen2. Fits 140/170mm length magazine tubes for 9mm/40. On a 140mm length tube, this will lock in ONLY on the full sized grips, and provides positive over insertion stop for slide lock reloads. Not for 120/126mm magazines in any grip module, as they will not lock in place.
Machined from 6061 aluminum and anodized matte black. Includes classic 10-8 features: serrated front for easier stripping and more tactile handling, scallops on side for stripping stuck mag, and dimples on the bottom for marking your magazine.
Fits Gen2 Tactical Advantage factory mag well or bare Gen1/2 grip module without mag well (see photo gallery). Does not fit 2019 Slim Tactical Mag well, nor is it intended for other magazine wells since each have unique internal profiles that make it impossible to achieve positive over insertion stop on all of them.
**The star will sit below flush due to our plate being thicker. The pad's hole location is set to minimum spec to eliminate any fore/aft play of the pad on the tube, but it can make for a very tight fit for the factory retainer (the star). Here the solutions to try if the star isn’t popping up into the base pad:
1) Hold the mag tube and rap the serrated front of the base pad on a wooden block, inertia usually is enough to seat the star retainer.
2) Use a larger diameter punch to push the star down and tilt it in order to have it pop up.
ReviewsTylerThese basepads are substantially better than the plastic basepads that come on 2011 mags, and a very reasonable price point. I didn't read the note about them only fitting the new magwell geometry, but with pretty minimal hand filing of my magwell (on a DVC Omni) they now fit and function flawlessly.
