This is a high-performance standard pressure 40 S&W loading, which means it is safe to fire in all 40 S&W firearms that are in normal operating condition.
The lightweight 140gr. all-copper Barnes bullet mushrooms readily, yet penetrates as deeply as a typical 180gr. JHP-style bullet. It delivers low recoil and fast velocities, aiding in quick and accurate follow-up shots. Expect approximately 13 to 14 inches of penetration in flesh and bone.
This load uses flash suppressed powder, providing a critical tactical advantage in low-light conditions—where most defensive shootings in the U.S. occur. Avoiding blinding muzzle flash during a life-threatening encounter can make all the difference.
We always use real-world firearms to generate our advertised velocities. Unlike the misleading industry practice of using extra-long test barrels, our data reflects what shooters can expect in actual conditions. With Buffalo Bore ammunition, you get the performance we promise—tested in real over-the-counter firearms.
Real-world velocities from standard pistols:
- 1,311 fps — Caspian 1911, 5-inch barrel
- 1,159 fps — Taurus PT99, 4.7-inch barrel
- 1,172 fps — Glock Model 23, 4-inch barrel
