Went with a 12.5 inch and a birdcage FH for my pistol build and can not tell any difference in noise from my 16 inch rifle, with normal muffs on. Not getting that concussion wave slap in the face like a large magnum handgun either. Seems pretty tame overall. Haven't had a chance to make an evening range run yet to compare muzzle flash but don't expect anything horrendous. Hoping a fancy muzzle device won't be necessary.
