From Silencer Shop:
One question that has always been a mainstay in our most-questions-asked category is whether a specific silencer will fit a specific gun. With threading looking similar, and acronyms being thrown around like hot tamales, we understand your plight. As the suppressor industry grows, it seems thread pitch options have too.

Details, which are kept up to date, are here.
