Lyman A-Zoom Snap Cap for .40 S & W Centerfire Pistol, Blue, 10-Pack

Use these blue snapcaps for safety training, function testing or safely decocking the firearm without damaging the firing pin. A-Zoom training rounds are much more than conventional snap-caps. They are precision CNC machined from solid aluminum to precise cartridge dimensions, then hard anodized for ultra-smooth functioning and long life.
