SIG V-Crown defensive rounds combine perfected material specifications and fine-tuned design innovations, including a stacked hollow point cavity, to deliver exceptional on-target energy with maximum weight retention and optimal expansion for ultimate stopping power. The SIG V-Crown stacked hollow point design provides a smaller additional hollow point cavity behind the main cavity. This design, along with V-shaped jackets skives and scores provides controlled, uniform expansion at all effective distances and velocities. Brass cases are TECHNI-CROM® coated for enhanced lubricity, superior corrosion resistance, and reliable feeding and extraction.
