All Pistol conversion kits bear a unique chamber profile that will not allow “Live/Lethal” Ammunition to completely chamber therefore holding the weapon out of battery, making the weapon inoperative. The conversions are also slotted on the side, which allows the brass case of a live round to rupture in a controlled manner dispersing gases and unburnt powder through the ejection port if all safety protocols are not followed or a round is distorted/forced into the conversion.
