The following is based on pre-release information for the canceled online game codenamed Project V13 and is not canon.
“The absolute BEST shotgun available! This should be called a “shotfun”! The best modern .12ga a shooter can buy (well, the only modern .12ga available), this is the model 42 with optional accessories mandatorily included. You get a suppressor, a scope and a beer coozie. If you’re looking for one gun to carry for any occasion, from clay shooting, Clay Jones shooting, to target plinking, this is the GUN FOR YOU!”— Crazy Ivan's description
