I just thought of this rig for IDPA Defensive Multigun. You’d be in Enhanced Pistol Caliber Carbine, and you’d also be the biggest stud on the range if you ran this.
Rifle: M1 Carbine with Ultimak Rail and Aimpoint.
Shotgun: Remington Model 11 in 20 gauge, like the Horrible Frankenshotgun I built.
Pistol: ParaUSA GI Expert ESP or STI Spartan.
You’re rocking an M1 Carbine, a Remington Model 11 and a 1911? Trust me, even if you don’t win your rig will make the ghosts of John Moses Browning and Jeff Cooper smile.
