SilentStrike is the ultimate performance subsonic round for LE, hunting, and concealed carry. SilentStrike, with its low recoil, is the best option for someone needing personal protection but having trouble handling the recoil of a larger caliber handgun. SilentStrike is made using a frangible tungsten powder metal core. Tungsten powder metal allows you to get deep penetration in soft tissue while the design of the core causes the projectile to fragment violently in soft tissue even at the slower subsonic velocities. Total energy transfer inside the target, causing hundreds of permanent wound channels, makes SilentStrike the ultimate subsonic round for CQB stealth operations where how quiet someone can be could determine life and death.
