Affordable: These were my dollars being spent, not a give away of demo deal.Easy to clean: My old YHM 3100 can is sealed and not the easiest to clean.I also included a list of attributes and went to work on research. When I first started looking for suppressors, I made a list of things that were important to me. So why this particular suppressor you ask? What makes it maybe the best 9mm suppressor on the market? Plus, there are more than a dozen quality manufacturers on the market. Right now, the market for suppressors is hotter than ever thanks to the BATFE allowing the use of the E-File system again for Form 4’s. That search lead me to the Rugged Suppressors Obsidian 9. I recently ended a long search for a new pistol suppressor.
