The barrel is threaded, but the the thread protector interfaces with the barrel bushing until a coupler replaces the thread protector? The coupler being female (threaded whatever the barrel is threaded) to male (whatever the suppressor is threaded)?

It’s an interesting idea to me because that would make the barrel to bushing fit easy to tighten up although the threading adds yet another tolerance to stack and part to shake loose.

For all the barrels I’ve seen threaded, I have yet to see a suppressed pistol at the range. I think it’s like putting a NOS sticker on your Toyota. Since I’m in a cranky mood, I will suggest that someone could make money by making a barrel bushing that has a fake .45 cal suppressor tacked on the end since 99.9 % of people will never get a can anyhow and 9mm would scoot right through.

I think the correct term is length of barrel and thread specifications. E.g., “5” .578x28 threaded barrel”
