Looking for insight on building a custom 9mm suppressor on an SBR, to duplicate a Colt 635SD.

Any websites able to give insight on building a custom, two part suppressor?

Thinking two parts: behind FSP on a 9mm AR barrel, bleed the gas. Front of FSP,  cut the sound waves.

Am I off base with my thoughts?

Might give you some ideas / inspiration. Down in thread are pics of assembly method.

After reading this thread, I already got some fresh ideas.

Brass grommets are now a thing indeed.
