Sub Sonic (SS) 9mm ammo
REcco on what Co's make the best SS 9mm FMJ 115 gr +
How does the round react with an equiped Silencer?
My intended usage is for emergency in home situation where the retort is of significant decibels to permanently impair hearing

Why not go to 147 gr.?? Lots of good sub sonic loads.

I can't answer your question but of course have to chime in with something. If a .45 acp is an option it is already sub sonic and the pistol is made to operate with it. I'm thinking you need to go with a heavy for caliber round in 9mm to both be subsonic and produce good energy a, .45 acp already does that.
If 9mm is what you have and need to use I certainly hope you find the right combination.

Hornady 9mm 147 gr XTP is subsonic and an excellent defense round.
It works well suppressed in my Beretta APX:
SIG P-320
CZ-10
The Walther PPQ required the use of a special spring (which Walther included):
The Glock 19 just doesn't run well with sub sonics:

Why do you always have to make me jealous, Mark? Very nice collection!

Don't the pressure changes when installing a silencer require a spring change in the firearm for it to operate properly?

Not in all of them. As I mentioned, the Walther PPQ required a spring change, but Walther provided the extra spring OEM. I've been playing around with springs for my Glock 19 seemingly forever, and with continued mixed results.
Keep in mind that virtually all modern centerfire handgun caliber cans contain their own spring which helps to overcome issues with pressure and failure to cycle due to the presence of the suppressor.
The suppressor on the left (which is made by GEMTECH) is designed for .45acp while the one on the right (made by Advanced Armament Corp.) is for 9mm Luger. Notice the difference in the sizes of the two springs. The .45 is like a garage door spring compared to the 9mm.
