Add a comp eh? that would make for one long pistol. I see Infinity team is using a 6" for their limited class gun
But it would be wonderfully loud with a concussion wave that would turn heads for miles.
It'd probably make a mess of steel targets that are anything less than AR500 though. I'd love to see what it'd do to a bowling pin.
It'd use the same slide and mags as a 10mm, so you could do both with a barrel swap.
