No you don't. Not to attack you personally but it's amazing how ignorant people are on this subject.
Shaking my head. Post 24, man. Situational awareness. LOL. Oooh, talk more military jargon, man. In home defense my Model 870 is creating "the situation".
Also, unfortunately, from a legal situation, it's probably usually better to have shot-or-killed someone with a gun that doesn't have a suppressor. It could create a lot of dumb questions during the investigation into the death afterwards. The lawyer of the victim will make a big deal about why you had a Class 3 device, and were playing Special Ops guy.
I'm genuinely not worried about being criminally prosecuted for shooting and killing an intruder. With regards to civil action, I'm more concerned with surviving a home invasion and defending my family than dealing with a scum-bucket lawyer.
The situational awareness thing is real. I probably spent 200 hours between Triple Canopy and CQD. One of the simulations we ran repeatedly on one trip was a home defense scenario where there were an unknown number of assailants (2-6). We alternated between wearing no hearing protection and wearing remotely triggered electronic hearing protection. In the latter case, after we fired our first shot the hearing protection was triggered and you couldn't hear shit. Guess how much worse our success rate was when we couldn't hear?
As an aside, simmunition hurts like a mother. It also doesn't cycle too reliably :p
Frankly, the suppressor laws we have in this country are nuts... and that's coming from a person who generally supports a bit more gun regulation.
