STI/SV/SPS 140mm Magazine 11 Coil Spring & Follower Kit by Grams Engineering

This ''Follower Kit'' includes a ''Grams Format'' follower (S2) and 11 coil spring. For use in STI/SV/SPS or CR mags that measure up to 145mm long (with base pad attached). 

  • 9mm, .38 Super, 38 Super Comp / TJ,  .40 S&W and .45 ACP calibers (no spacer in magazine)
  • 9mm (requires a spacer in magazine, older STI magazine tubes)

Grams Slide Lock Function

This "Follower Kit" is pre-tuned and requires no modifications for proper feeding function in a magazine tube of correct tolerances. The follower is designed for slide-lock function, but due to tolerance stacking of all of the slide lock system parts, modification of these parts may be necessary for proper function. Tuning of the mag tube may be required if the desired reliability or round count is not obtained.
