Question about threaded “barrels”
I have a mostly hypothetical question about RCW 9.41.010.
RCW 9.41.010 states, “…A semiautomatic pistol that has the capacity to accept a detachable magazine and has one or more of the following:
(A) A threaded barrel, capable of accepting a flash suppressor, forward handgrip, or silencer;…”
IF someone were able to thread the slide or barrel bushing, and not the barrel, would that be legal?
For example, in the late 40s, the soviets experimented with suppressing the Tokarev TT-33 by installing a threaded barrel bushing, not a threaded barrel, and installing a suppressor onto the bushing. Would this not be illegal in Washington state, since the barrel itself isn’t threaded?
What do you all think?
