Nosler 51286 Assured Stopping Power 9mm Luger 124gr JHP Ammo - 20 Rounds

The Nosler 51286 Assured Stopping Power 9mm Luger ammunition pairs a 124-grain jacketed hollow point bullet with the meticulous quality control Nosler has built its reputation on. If you're looking for 9mm handgun rounds that emphasize consistent performance and reliable expansion, this 20-round box delivers the precision manufacturing you'd expect from a premium ammo maker. Built on Nosler brass and loaded to exacting standards, each round is individually inspected to meet the same rigorous benchmarks Nosler applies to its match-grade offerings.

Self-defense and duty shooters often gravitate toward purpose-built ammunition, and the JHP design here is engineered for stopping power when it matters. The 124-grain weight sits in the sweet spot for 9mm—offering a balance of velocity and energy without sacrificing the inherent advantages of the caliber. At 1200 fps muzzle velocity and 396 ft-lbs of energy, this load delivers predictable ballistics from standard 9mm pistols. Whether you're stocking up for the range or keeping defensive ammo on hand, knowing exactly what you're getting matters; Nosler's attention to brass prep, powder weighing, and round-to-round consistency means less variation shot to shot.

Nosler has long prioritized quality over volume. Every piece of brass in this load is checked for length, neck-sized, chamfered, and inspected for flash hole alignment before being paired with the bullet. Powder charges are weighed individually, and finished rounds get a final visual inspection and polish. That level of care in a factory round is uncommon—most shooters associate it with hand-reloaded ammo. It's the kind of attention that keeps your shooting predictable and your firearm running smoothly.
