I'm a huge fan of suppressors. Oddly, countries that strongly restrict gun ownership often do not restrict suppressor ownership /use. Several years ago I studied this topic, but don't know if my info is still up to date.

I've always felt a suppressed 22LR handgun would make an ideal "SHTF" pack gun, because you can hunt with it undetected. I'd still want a full-power rifle, but having a 22 in the ruck allows you to hunt / carry lots of ammo for little weight.

Worst Case Scenario = Liberator Pistol.

The United States made tons of "Liberator" 45acp handguns and air-dropped them in Europe during WW2. The purpose of the cheap / crude Liberator was simple....you used it to liberate a better gun from the enemy. A suppressed 22LR could be used as a Liberator if all else failed....
