These spacers are necessary for 9mm applications when using 38 Super STI mags and preferable for all 9mm applications, including use with SV magazines. It never hurts to push the bullet nose as close to the feed ramp as possible for enhanced reliability. Recommended for use in conjunction with the Grams FKS9-13 spring kit. Spacers may require minor fitting to match exact mag shape and length. The stainless spacer requires beveling the back edge, on both the top and the bottom of the spacer for best performance. Available for 140mm and 170mm magazines.
