Carlson Snap Caps for .410-gauge shotguns let you practice dry-fire training and malfunction drills without the wear that live ammunition creates on your firearm's mainspring and firing mechanism. Built from aluminum, these dummy rounds won't mar your chamber, extractor, or ejector, while the primer insert matches the proper hardness to prevent striker damage. Each snap cap is manufactured to SAAMI specifications for reliable fit and function, making them an essential training tool whether you're a competitive shooter refining your technique or a self-defense-minded gun owner developing quick response skills. The bright red finish makes it easy to distinguish these training rounds from live ammunition. Includes one snap cap per unit.
