Ironwood's gun is the fabled gun-gun, both a revolver AND a semi auto.

Notice his gun has two triggers, and he uses two different typs of ammunition without ever changing the loaded rounds.

You could go with the Arsenal Firearms 2011-A1 if you want a double barrel semi auto pistol that is a bit more specific than "two baratteas glued together" but that's entirely up to you.
