FTX® Bullet Technology

The patented FTX® bullet expands reliably and resists clogging when fired through heavy clothing.

Defense-Centered Design

Critical Defense® ammunition was developed to provide the best performance for defensive or personal protection situations and is the ultimate choice for any short barreled, concealed carry style firearm. Bright nickel-plated cartridge cases simplify chamber checks in reduced light, and low-flash propellants help preserve night vision.


Details such as nickel-plated cases that resist corrosion and optimized propellants that burn quickly to reduce recoil and limit muzzle flash, help ensure that Critical Defense® ammo is dependable in every situation.
