20 Rounds of 180gr JHP 10mm Ammo by Sig Sauer

The 10mm is an immensely powerful cartridge – but brute force alone isn’t always enough. You want a self-defense round with a bullet that’s solely designed for self-defense. In other words, you want a round loaded with Sig Sauer’s V-Crown jacketed hollow point.

This round’s 180 grain JHP is designed to pierce barriers and soft tissue without breaking apart. In addition to preserving the bullet’s seating depth, the V-Crown’s special toothed cannelure mechanically locks its core and jacket together so the two components can retain the combined weight they need to penetrate deeply.

The V-Crown’s tough lead-alloy core is divided by a series of radial scores. These help its nose cavity produce a more uniform mushroom, and its jacket is also skived so it can split apart evenly as it guides consistent terminal expansion.

The V-Crown is socketed in a nickel-plated brass case, which boasts higher resistance to corrosion and enhanced lubricity to promote surer feeding and extraction in a semi-auto. Sig also formulates this ammo’s propellant to produce very little muzzle flash, which will help keep your eyes acclimated to a dark setting.
