The Grizzly Ammo 357 Sig 125-grain FMJ flat point round delivers consistent, reliable centerfire handgun ammunition for shooters who demand dependable performance at the range or in the field. Built by Rintoul (under the Grizzly Ammo brand), these rounds pair a full metal jacket construction with a flat point design—a combination that balances penetration, feeding reliability, and practical accuracy across 357 Sig platforms. Whether you're zeroing a duty gun, running practice drills, or stocking reliable backup ammunition, this load offers the straightforward performance serious shooters expect.

357 Sig has carved out a loyal following among law enforcement and civilian shooters alike. It bridges the gap between 9mm and .40 S&W in terms of velocity and energy, and the flat point profile aids feeding in some platforms while supporting consistent expansion characteristics where barrier performance matters. Grizzly's FMJ construction prioritizes jacket-to-core integrity for predictable ballistics downrange.

This product ships as a bulk case pack—200 rounds total (ten boxes of 20)—making it a practical choice for serious training cycles, departmental practice, or building a reliable inventory of proven ammunition. Each 125-grain projectile is loaded to consistent specifications, supporting the accuracy and confidence you need for repeat shooting.
