Hornady Critical Defense fires a 185-grain FTX bullet at 920 fps from a .45 Colt case, generating 348 ft-lbs of muzzle energy. The FTX (Flex Tip eXpanding) projectile has a red polymer tip seated in the hollow point cavity that prevents clogging from clothing or other barriers. Nickel-plated brass cases resist corrosion and feed smoothly in the dark by feel, both practical features for a defensive round.

The polymer tip is what separates Critical Defense from standard JHP ammunition. When the bullet strikes soft tissue, the tip is driven back into the hollow point, forcing reliable expansion even through heavy denim and layered winter clothing. At 185 grains and 920 fps, this load moves faster than most .45 Colt defense loads in the 225-250 grain range, which translates to flatter trajectory and quicker time to target. The lighter bullet also generates less felt recoil, allowing faster follow-up shots from a single-action revolver.

Hornady designed this specifically for concealed carry and home defense in .45 Colt revolvers. The consistent expansion through barriers makes it a strong choice for shooters who rely on a revolver as their primary defensive firearm. It pairs well with shorter-barreled revolvers where velocity loss would normally hurt hollow point expansion, since the polymer tip ensures the bullet still opens up at lower speeds. For .45 Colt owners who want modern defensive technology in a classic cartridge, this is one of the top options available.
