Grams FKS-11 Spring and Follower Kit for 2011 STI/SV/SPS No Spacer
Calibers: 38/9mm, .40, 10mm with no spacer plate
Package Includes: Grams S1 follower and 11 coil spring
The same follower works in both STI, SV, SPS, CR 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. The follower is the same for all calibers(except 9mm with Spacer). Only difference is the length of spring. Use the 11 coil for magazines UP TO 145mm with flat base pads in both 38 and 40.
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.
Please Note: Although listed by the manufacturer as springs for Gen 1 and Gen 2 STI Magazines, we believe this will not work reliably for Gen 2 without Magazine Tuning
