Our Snap Caps are designed for safe release of firing pin springs, featuring a spring-loaded striking area that cushions and protects firing pins. Each package includes (2) Snap Caps, making them an excellent tool for teaching proper shooting techniques and eliminating flinching. These precision-machined caps adhere to true SAAMI specifications, with primer material designed to prevent striker over-protrusion. The aluminum construction ensures that your chamber, extractor and ejector remain undamaged. Snap Caps are an essential training aid for quickly learning how to address malfunctions, making them invaluable not only for competition shooters but also for anyone who uses a firearm for self-defense.
