Specifically designed for safety training, function checks, jam-clearing drills, and dry-fire practice, the A-Zoom® 9mm Luger Snap Cap set is constructed of anodized aluminum for lasting service, superior corrosion resistance, and smooth feeding performance, and features soft, inert Dead Cap primers for safe, damage-free dry-fire performance. Better yet, these snap caps are similar in weight to standard ammunition, making them ideal for realistic function testing and relieving spring tension. Includes 5 snap caps.
