Pachmayr trusted A-Zoom Snap Caps, perfect for training, now conveniently packaged to meet your specific needs! For safety training, function testing or safely de-cocking 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. Each round has A-Zoom's remarkably durable Dead Cap proven to withstand over three thousand dry fires while protecting the firing pin.
