Even though the old SV mags and the new STI 9mm mags supposedly don't need spacers, my gunsmith says 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. For maximum performance and reliability, the stainless spacer requires beveling the back edge, on both the top and the bottom of the spacer for best performance. Call us for details on fitting if necessary. Available for 140mm and 170mm magazines.
