CorBon Self Defense .357 SIG 125 Grain JHP Ammo - 20 Rounds

CorBon Self Defense .357 SIG 125 Grain JHP ammo brings proven stopping power to a cartridge built for serious defensive carry. The .357 SIG sits between the 9mm and .45 ACP in capability—faster than a .45, hits harder than most 9mms—and CorBon's jacketed hollow point loads are engineered to maximize what the caliber can do. This is the ammunition that established CorBon's reputation decades ago, and it remains a trusted choice for shooters who want reliable performance when it matters.

The 125-grain JHP uses both internal and external serrations combined with a soft lead cavity to promote consistent expansion while maintaining adequate penetration. That combination is what separates defensive ammunition from plinking rounds: you need expansion for energy transfer, but you also need penetration to reach vital zones through clothing, glass, or barriers. CorBon's design targets a penetration window of 9 to 15 inches in ballistic gelatin—deep enough to be effective, controlled enough to minimize over-penetration risk in civilian environments.

Each box contains 20 rounds, sized for shooters who practice with what they carry and want quality ammunition at the range without burning through inventory. Whether you're testing a new defensive pistol, validating load performance in your carry gun, or maintaining your practice regimen with proven ammo, CorBon delivers the consistency you expect from a brand with serious pedigree in the defensive ammunition space.
