Been thinking about a can for home defense. With kids and dogs, worse case senecio shooting in a house is extremely loud. Is their a big difference hearing wise between 9 or 45 can. I'm talking caliber specific suppressor here. Was dead set on a 45 with can but am starting to think maybe 9 with can is better. I can look at stats all day but want opinions from people who have shot with either. I'll talk to Jake about it too since I have a 5.56 can I'll have to pick up from him eventually
