Sierra Sports Master Handgun Bullets .355/9mm .355" 125 gr JHP 100/ct

Sierra Sports Master Handgun Bullets in .355/9mm caliber represent a proven platform for shooters demanding consistent, reliable performance across diverse velocity ranges. These 125-grain jacketed hollow point projectiles are engineered with a serrated power jacket design that delivers controlled, uniform expansion upon impact. The serration geometry initiates separation along predetermined lines, maximizing energy transfer to the target while maintaining predictable weight retention—critical factors in duty, defensive, and training applications where shot placement and terminal performance intersect.

The 125-grain mass in 9mm strikes a proven balance between velocity maintenance and recoil management. This weight class pairs well with standard 9mm powders and primers, enabling reloaders to achieve velocities ranging from subsonic to full-power loads without velocity-dependent expansion failures. Sierra's hollow point construction and serration system are designed to expand reliably from 9mm velocities that span from approximately 900 feet-per-second to 1,300-plus feet-per-second, making this load suitable across a wide spectrum of barrel lengths and powder combinations. The 100-count package—approximately 1.82 pounds—is practical for high-volume training blocks, match preparation, and reloading economy.

Law enforcement, military personnel, competitive shooters, and serious reloaders rely on Sierra Sports Master projectiles for their established track record in self-defense and duty ammunition development. This 9mm hollow point configuration is used by departments and trainers who prioritize repeatable results and minimal variance shot-to-shot. Whether loading for primary duty weapons, backup systems, or cross-training with off-duty carry platforms, the .355" diameter and 125-grain specification deliver the consistency that tactical environments demand. The 100-round container supports both single-session testing and longer evaluation periods before committing to larger quantities.
