Silencerco makes good suppressors, the designer quit and started his own company Dead Air, the Silencerco Omega 300 is the one you want. I have a Harvestor as well, to big for a pistol it's designed for hunting rifles.
There are many video's on youtube where they use decibel meters and compare the reports, Silencerco models either tie or beat nearly every other manufacturer. As a plus they're usually cheaper as well. Griffin armament makes one that's on par with the Omega, other than that it's Silencerco all the way for me, I have 6 of them.
Best bang for the buck.
