This is 9mm +P+ ammunition. It is so overpressure that SAAMI doesn’t even define specifications for it. This ammo is quite likely to destroy an antique firearm. Do not fire it unless you are certain your firearm can handle its ferocious chamber pressure.
Let’s boil it down to math. A standard pressure 9mm cartridge loaded with a 115 grain bullet can easily exhibit 1,175 fps muzzle velocity and 353 ft lbs muzzle energy. But this is a 9mm +P+ cartridge, which has a 147 grain bullet that achieves 1,175 fps muzzle velocity out of a 4” barrel. That places its muzzle energy at 451 ft lbs. In simpler terms, it hits approximately 25% harder than a standard pressure equivalent can at the same muzzle velocity.
This round’s jacketed hollow point bullet is made by Sierra. Its skived jacket permits reliable expansion at lower velocities, as well as a reduced risk of over-penetration. It feeds reliably, flies accurately, and plunges to an effective depth for defense and predator hunting. All in all, it’s a bullet that deserves the shooter’s full confidence.
Underwood loads pistol ammunition in the USA using low-flash propellant and low-friction nickel-plated brass cases. This ammo’s recoil is far from gentle, relatively speaking – but it’s totally worth it, when your goal is to inflict as much damage as possible with a 9mm firearm.
