Sig Sauer V-Crown Ammunition is cold-formed, lead-free and cased in brass. Sig Sauer V-Crown rounds feature a consistent "V-shaped" main cavity and a smaller "V" shaped secondary cavity. Material specifications and design are perfected, Sig Sauer V-Crown .380 ACP ammunition stacks two cavities together. The result is a greater wound channel - and thus greater stopping power - and consistent overall performance from Sig Sauer V-Crown .380 ACP ammo that is dependable in the field as well as in the range.
