The Traditions ASC40 Snap Caps are meticulously designed to increase the lifespan of your firearms. They aid in alleviating the pressure on both your firing pins and firing pin springs. It\'s highly recommended to insert a snap cap in the chamber of your stored, unloaded gun and then fire your rifle. This enables the firing pin to rest, reducing the risk of potential breakage in the future.Beyond their protective qualities, snap caps serve as an exceptional tool for dry firing practice. They help foster safe gun handling, enhance your shooting skills, and fine-tune your trigger. This specific handgun model features a plastic casing and the package includes six (6) Snap Caps for your convenience.
