Fiocchi Aero Defense Dynamics 12 Gauge 2-3/4in Slug 1oz Shotshells - 10 Rounds - "The right tool for the job" is always sound advice, and that includes defensive firearms. Serious defense practitioners understand that personal safety requires 24/7 vigilance in all environments. That means multiple firearm platforms suited for specific needs - from deep concealment micro pistols and snub-nose revolvers for discrete public carry to defensive rifles and shotguns in the home or on the road. Filling all those magazines and cylinders with reliable-performing defensive ammunition can be expensive, especially when dealing with multiple calibers and chamber gauges. That's why Fiocchi developed its Defense Dynamics line of ammunition. Defense Dynamics cartridges are built with the same quality cases, hulls, powders, and primers that experienced shooters have come to expect from Fiocchi ammunition while employing projectiles proven to deliver the kind of terminal performance you demand in a personal or home defense round. With a focus on jacketed and semi-jacketed hollow points, buckshot, and slugs, the Defense Dynamics line delivers professional results for price-conscious defensive ammunition.
