Buffalo Bore 45 ACP +P ammo chambered in 230 grain jacketed hollow point pushes 950 feet per second from a five-inch barrel, delivering 461 foot-pounds of energy on target. This is an overpressure load built for defensive carry in modern handguns that can withstand the additional slide velocity and recoil impulse generated by +P pressures. If you’re running a 1911, Springfield XD, or Glock 21 in normal operating condition, this round provides terminal expansion and penetration above standard-pressure loads without requiring firearm modifications — though Buffalo Bore recommends upgrading your recoil spring if you plan to shoot more than two boxes in a single range session.
Built for the Box
Each round is assembled with a 230 grain jacketed hollow point projectile, a design that balances penetration depth with controlled expansion in tissue and ballistic gel. The brass case is Boxer-primed and reloadable, non-corrosive. Flash-suppressed powder keeps muzzle signature low in dim light, preserving your night vision if you’re forced to fire after dark. Buffalo Bore loads to maximum SAAMI +P specifications — this is not reduced-recoil training ammo. Expect sharper felt recoil and faster slide cycling compared to 230-grain ball or standard-pressure hollow points.

This load is dimensionally identical to standard 45 ACP — it will chamber and fire in any gun marked .45 ACP. The difference is internal pressure, which peaks higher than SAAMI standard-pressure ceilings. Do not use in vintage 1911s manufactured before 1950, alloy-framed pistols not rated for +P, or firearms with cracked slides or worn locking lugs. For modern carry pistols in good condition, this round provides a velocity and energy boost over 830-fps ball without crossing into the mechanical stress zone that shortens frame life.
