Underwood Ammo Handgun Ammunition Features Underwood Ammo Handgun Ammunition in 9mm +P is loaded to higher pressure than standard 9mm ammunition pushing a 124 grain full metal jacket bullet to 1225 feet per second for 413 ft lbs of muzzle energy. This added velocity gives shooters flatter trajectories and more consistent cycling in pistols rated for +P pressures. The full metal jacket bullet construction made from copper and lead ensures smooth feeding through semi-automatic magazines and minimizes the risk of feeding malfunctions during rapid fire strings. Cases are made from nickel plated brass which resists tarnishing in long term storage and extracts cleanly from the chamber after firing. This load is rated safe for use with a suppressor making it a versatile option for both open range shooting and suppressed training sessions. Supplied 50 rounds per box this ammunition is well suited to high volume range days where consistent performance matters. For 9mm shooters looking for a step above standard pressure ammunition this Underwood Ammo +P load is available for sale at GrabAGun.
