Jacketed Hollow Point (JHP) ammunition for the .357 Sig is designed for maximum stopping power. When the nose of the bullet contacts a target, the weight and energy of the bullet carry through, filling the hollow cavity and causing the bullet to expand massively. This expanded diameter creates a wider wound channel and offers more effective stopping power. The effect of this expansion actually makes hollow point bullets safer because the energy of the bullet is delivered more rapidly, decreasing the risk of bullets passing through your target. Thanks to the design of the .357 case and bullets, JHP ammunition feeds exceptionally reliably.
For these reasons, JHP bullets are an ideal choice for personal and home defense, but you should always practice with your defensive ammunition so you can count on its performance when your life depends on it.
