My shooting team requires that we have safety flags for our guns. These flags prevent ammo from being in the chamber when the flag is in place. However, the only flags available for this gun do not prevent ammo from being in the chamber. These other flags prevent the firearm from firing but do not prevent ammo from being loaded in the first place. This model has dowels that extrude into the bullet well to prevent ammo from being loaded while this flag is in place.
