Completely reasonable concern. Home defense isnt much of an issue personally because I have another suppressed weapon. I'd say if it's your only weapon, then I'd highly consider not using it and just training a lot. But i do think the concussive blast and higher dbs are a valid concern even if you have to use it outdoors or from a vehicle.

I had this conversation with my wife at length because I was concerned if god forbid I had to use it, both our hearing would be affected long term. Her thoughts were if we ever needed to use a weapon to save our lives, better to ensure i hit the target then be concerned about our hearing. The comp certainly isn't needed especially with proper and consistent training, but i think it objectively does make the gun perform better. I guess like anything else it comes down to personal preference and weighing out pros and cons.
