Sierra Bullets V-Crown 9mm 125Gr JHP .355 Diameter - 100 Rounds (Model 9925)

The Sierra Bullets V-Crown 9mm 125Gr JHP is a purpose-built handgun bullet designed for reloaders who demand reliable expansion and consistent accuracy in defensive and target loads. Developed in partnership with SIG Sauer, this .355 diameter projectile combines Sierra's precision manufacturing with a stacked hollow-point design engineered to perform at practical defensive distances. The 125-grain weight hits the sweet spot for 9mm: fast enough for velocity but heavy enough to carry energy downrange without sacrificing shootability.

What sets the V-Crown apart is the cannelure halfway up the shank—a locked groove that binds the jacket to the core to maximize weight retention during expansion. That matters. A bullet that sheds pieces loses energy and predictability; this design keeps the projectile together while the hollow point does its job. The additional hollow-point cavity enhances controlled expansion across a range of velocities, so whether you're working up loads for carry or practice, performance stays consistent.

These are component bullets—you'll need reloading equipment, dies, brass, powder, and primers to complete the cartridge. If you're already set up to reload 9mm, you know the value of starting with bullets engineered for terminal performance rather than settling for whatever is on the shelf. Sierra's reputation for accuracy holds true here, and the V-Crown design proves that defensive performance and precision aren't mutually exclusive.

Frequently Asked Questions

What is the V-Crown hollow point design?

The V-Crown features a stacked hollow-point cavity combined with a cannelure (locked groove) halfway up the bullet shank. The cannelure bonds the jacket to the core, ensuring the bullet stays together during expansion rather than fragmenting, which preserves energy and terminal performance.

Are these bullets for reloading only?

Yes. These are component bullets sold for handloaders. You will need reloading equipment, brass casings, powder, and primers to assemble finished ammunition.

What firearms are these bullets for?

These .355 diameter, 125-grain bullets are sized for 9mm firearms. They are component projectiles compatible with any standard 9mm reloading setup.

Why 125 grains for 9mm?

The 125-grain weight balances velocity and energy for reliable expansion at defensive ranges while maintaining low recoil and shootability compared to heavier projectiles. It's a popular choice for both practice and carry loads.
