I shoot a Sig P226 with a Trident9 suppressor. I have two complaints about my setup. One is the particulate crap that gets shot back at me from the recoil-booster device. The other is the tall suppressor sights I put on my P226.
If you are using a 92fs I have heard that you can use a 10 pound recoil spring and not have to use a recoil-booster (LID, Nielsen device, whatever). You will have to use a regular weight spring when shooting without the can.
As far as the sights go, I bought some AmeriGlow tall suppressor sights and they make my gun shoot about 6 inches high at 10 yards.
Stopping power: The power some guns have to make you stop what you are doing and get your wallet out.
