Truly an innovative idea, these training barrels from Blade-Tech were created to give you the opportunity to train with your own weapon, rather than a colored training gun. Molded in bright yellow, high-impact plastic, the Training Barrel replaces your factory barrel. It affirms its presence by showing bright yellow in the ejection port and muzzle, yet allows you to work the slide, safety(s) and load/drop magazines like normal. The Training Barrel is installed just like you would install a factory barrel.
