Started in 2015, Keystone Munitions was formed with the intention of providing premium ammunition to the great state of Pennsylvania and surrounding areas. Family owned and operated, the goal was and will always be to provide premium ammunition while providing some of the best prices. One thing is for sure, we will never sacrifice quality over price, no matter the cost.

Keystone's 9mm DEFENSIVE ammunition was designed to be the most effective round for penetration, using a 90 gr. LEHIGH DEFENSE EXTREME DEFENSE PROJECTILE. The Xtreme Defense (XD) Technology is based on the popular Xtreme Penetrator product line. The design goal was to achieve the same barrier performance and massive permanent wound cavity and reduce the penetration depth to coincide with an individual's personal comfort level. The XD ammunition has an optimized nose flute, total weight, and velocity to achieve a penetration depth range of 18 inches with a permanent wound cavity (PWC) that is just simply enormous; no other expanding hollowpoint comes close to achieving anywhere near this diameter and volume. Not only is the PWC over 100% larger than any other expanding bullet, it is near barrier blind, ignoring wallboard, sheet metal, and automotive glass. Lehigh was able to accomplish this quantum leap in terminal performance at the same time while reducing recoil. The terminal performance achieved is quickly approaching that of 5.56 rifle performance and that is an incredible feat.

This ammunition is new production, non-corrosive, in boxer-primed, reloadable nickel plated brass cases. 1 box of 20 rounds.
