Grams Spring/Follower Kit 11 Coil STI/SV

Other products by Grams Engineering

Item #: FKS
Our Price: $18.90


The same follower works in both STI and SV mags. These new kits use a unique locking system to keep the follower from coming off the spring. The follower and the spring have been completely redesigned for better reliability and longer life. These are a must have for any serious shooter. These will not work in the new STI 10 round mags which take a narrower spring. The follower is the same for all calibers(except 9mm with Spacer). Only difference is the length of spring. Use the 11 coil for 140mm or less mags with flat base pads in both 38 and 40. Use the 13 coil for 140mm mags with extended base pads(7, 8, or 11mm) or 170mm mags.

Important Info- Grams followers are designed to allow you to tune the follower to your gun and mags for slide lock. If you do not want to tune your follower and want slide lock back do not buy these followers. Without tuning they may lock back with 1 round in the mag. This gives you plenty of room for adjustment to fit your particular equipment. If you do not want slide lock back just trim slide stop tab or Follower shelf to bypass Slide stop tab. 11 Coil

Turns out these add +2 using Taylor bases bringing up to 23...which is pretty sweet on a 140mm

These springs and followers allow me to feed my gun custom loads or off the shelf factory crap one can find these days.... and it likes to  eat everything.
