Buffalo Bore's Buffalo-Barnes Strictly Business is a high-performance .45 ACP +P round designed for defensive use with real-world performance in mind. The 185-grain lead-free Barnes TAC-XP all-copper bullet features a large hollow-point cavity that mushrooms reliably while maintaining deep penetration. Because the bullet is solid copper rather than a traditional jacket-and-core design, there's virtually no weight loss during expansion, meaning terminal performance stays consistent through various barriers.
One key advantage of all-copper construction is how it behaves when it needs to pass through intermediate barriers like denim, leather, or car glass. The solid copper body doesn't fragment the way some jacketed bullets do, so the round maintains its trajectory and energy delivery. Expect roughly 13 to 14 inches of penetration in tissue, which sits right in the effective range for defensive applications.
This load uses flash-suppressed powder that significantly reduces the visible muzzle signature in low-light situations. That matters because most defensive encounters happen when light is low and your eyes are already struggling to adjust. A bright muzzle flash from the first shot can actually work against you by destroying whatever night vision you had left. With this round, you keep your vision intact for follow-up shots.
The 185-grain bullet weight is lighter than standard .45 ACP loads, which translates to higher velocity at 1150 fps, less perceived recoil, and faster sight recovery between shots. For follow-up accuracy in a defensive encounter, that's a real advantage. The +P pressure rating gives you more power than standard loads while still being dimensionally compatible with any standard .45 ACP firearm in normal working condition.
+P ammunition is dimensionally identical to standard .45 ACP and will chamber in any .45 ACP firearm in normal operating condition. However, the higher pressure creates increased slide velocity, so if you plan to shoot multiple boxes of +P ammo regularly, consider upgrading your recoil spring to handle the extra force. This is especially important for older pistols or those with lighter springs.
All-copper construction means there's no jacket to separate from a lead core during expansion. The bullet retains nearly 100% of its weight, which keeps it heavier and more stable when passing through barriers like clothing or vehicle glass. The solid design also means the bullet won't break apart unexpectedly, giving you more consistent terminal performance in real-world scenarios.
Most defensive situations occur in low light, and a bright muzzle flash can destroy your night vision right when you need it most. This load's flash-suppressed powder significantly reduces the visible signature, which means you keep more of your natural vision for follow-up shots or to track threats. It's a tactical advantage that standard loads don't offer.
The lighter bullet weight gives you higher velocity (1150 fps) compared to traditional 230-grain loads, which means less recoil and faster sight picture recovery for quick follow-ups. You still get excellent penetration at 13-14 inches because the Barnes TAC-XP expands reliably at these velocities. It's a solid middle-ground choice that balances speed and stopping power.
