I have a YHM R9 that I really like. But I’m looking for another 9mm can to add to the collection. Will be used on SP5/AR9/MPX platforms. What would some of the top recommendations be?

Read all the threads in this forum asking the same thing.

The R9 is pretty damn good for what it is. Not saying it's the best, but it seems like many people that have experience on different suppressors are very impressed by it (see this thread here for example https://www.ar15.com/forums/Armory/What-s-the-quietest-9mm-suppressor-/20-538549/?page=2 ). With that in mind, I plan to keep mine as a dedicated PCC suppressor and have no plans to get another PCC suppressor at this time as I only have one host for it. If I get another 9mm PCC, I'll swap it to 3-Lug.

Otherwise, people highly recommend the Wolfman for a PCC but it's gonna cost you some $$$ compared to the R9.
