Product Overview

When YHM engineers set out to make a suppressor, they look far beyond that of just making the designated caliber quieter. They make it work across the board so that you, the shooter, can enjoy versatility across your entire arsenal all at a budget friendly price while maintaining that rugged durability you’ve come to expect from YHM®. This was the intent with the R9® 9mm. The primary goal was a 9mm suppressor capable of handling high volumes of fire and the ability to run other calibers such as .300 BLK and .308 Win. It was primarily focused on suppressing 9mm (specifically sub-machine guns and SBRs). The R9® is capable of being used on a handgun in conjunction with our Nielsen Booster Assembly.

    Amazing sound suppression for small size.

    Posted by Quiet ! on Aug 16th 2021

    I bought this for a CZ Scorpion pistol. Truthfully I have not put it on anything except for this pistol. I like every gun to have its own suppressor. On this specific host, the R9's suppression is as good as anything I have put on the gun, and I have tried plenty. An Osprey, Octane, Tirant 9, Rev 9, and even a Coastal Gun MIMS, (a huge 9mm suppressor). Nothing sounded quieter to my ears. Not that I could discern anyway. Now take into account this thing is tiny. It looks amazing on the end of the gun. So compact and yet so quiet. Add to this a price that is unmatched in the market place. YHM has re-invented itself in the Suppressor market. Tubeless, lightweight, and short welded baffle cans are where its at! If your lucky enough to find one of these in stock, don't hesitate a second.
