Snap caps serve as excellent tools for safety training, function testing, or safety de-cocking without damaging the firing pin. A-Zoom provides the highest quality snap-caps on the market, using precision CNC machined aluminum for perfect chamber fit and durability without any damage to the firearm from prolonged use. A robust pin stop at the rear of the cap allows for safe transfer of energy from the firing pin to the snap-cap, allowing for extensive dry-fire practice without the concern of excessive wear to the firing pin. These snap caps are compatible with all .45 ACP/Auto firearms. 10 snap-caps are included and feature a bright blue finish to distinguish them from live ammo.
