In for education.
It doesn't necessarily have to be heavy, they make a lot of titanium cans now.
But a 5.56 or 7.62 on burst puts out a very powerful pressure bubble that will easily strip threads and launch suppressor end caps a hundred yards. I've seen a lot of old school STEEL cans blow their welds if you burp a gun fast enough and often enough with rifle caliber pressures.
Basically anything that can be secured by hand can be blown out by sustained rifle pressures. This is why it is mostly .22 and handgun caliber cans that can be broken down but those 9mm and 45 cans typically aren't rated for full auto.
That is what it really comes down to. And if the mount isn't solid, it will fail at the mount and I've seen a couple suppressors launched down range because they weren't mounted properly or the mount was junk and then finally if the host weapon really isn't meant for full auto putting a suppressor on it will pretty much guarantee that it will beat itself to death.
A lot of otherwise perfectly fine 1911s had their lives dramatically shorted by a suppressor. That additional back pressure will absolutely slam them to death. This is why the Mark 23 concept wasn't built around a 1911 design.
So with a suppressor you are basically containing pressure and it is going to travel the path of least resistance. If the can is a joke it's going to blow up like a balloon or grenade. If the mount is a joke, it's going to lauch the can like those old water pressure rockets we used to play with and if the host firearm is a joke it's gonna run the bolt or slide at mach III and bottom out on whatever end of travel features the firearm incorporates.
Only a few designs such as the Ultimax or Knights belt feds never have this problem.
It's hard to be a ACLU hating, philosophically Libertarian, socially liberal, fiscally conservative, scientifically grounded, agnostic, porn admiring gun owner who believes in self determination.
Chuck, we miss ya man.
