What's the easiest handgun caliber to suppress?
I have 3 handguns, an XD 4",an XD Subcompact, and an M&P Pro, 5" all .40S&W. but I dont mind adding a gun to the safe. I can add a caliber as well. The reason I asked, is because I was watching a couple suppressor videos and learned of a Neilson device that was needed for barrels with a Browning action, that is, those that tip up when not in battery.
Are there home made kits for these blowback devices, like the maglite cans people use? I don't mind buying a gun, but I would prefer to save the money for the stamp by building the can myself. I want a suppressed pistol as a go to self defense gun at home.
So, back to the original question. What's the simplest route to go with a suppressed handgun?
