This .357 SIG caliber Safe Chamber Indicator (SCI) is made of Nylon 6/6 plastic. It is designed to fit perfectly into the chamber of your firearm, allowing you to cycle and dry fire your weapon. It has a bright “safety yellow” 12.5″ extension that is long enough to protrude out of the end of the gun and flexible enough to bend so the gun can be stored in its case or in a gun safe.
Use Ammo-Safe in conjunction with your trigger lock to ensure that your gun is secure AND safely unloaded.
Perfect for your Sig Sauer MPX .337, or any other submachine gun that uses a .357 SIG cartridge.
