Ah, the flaming pig.
Careful if you ever choose to suppress your 7.5" - I have a buddy that blew up a can because it wasn't "rated" for barrels under 9". He has bad luck with cans in general though.
My next shorty will definitely be a .300 BLK. After quite a bit of research I'm sold on the round - velocity loss from a 16" barrel vs a 9" barrel is almost negligible.
