Just ordered a new fx impact help!

So I've decided that I need another FX gun. Not that I am dissatisfied with the Fx wildcat I just think I need another one. So last night I ordered a two-tone Fx impact in 22 caliber does anyone know if I can fit a hugget moderator to the impact? and would it be wise for me to get the 30 caliber hugget so 
that it will fit any caliber that I use. I'm just wondering about noise control here how much louder is a 30 caliber Huggett shooting a 22 through it.
 
I just tried 3 Huggetts right now back to back on a wildcat .22. 1. .22 specific Belita. 2. .30 specific regular size. 3. .22 specific regular sizeSound levels from loudest to quietest. Belita loudest and higher frequency pitch (but quiet enough for back yard scenario and not much louder than regular size). .30 and .22 equal level of sound but the .30 is a lower frequency. Interesting findings. For pure stealth, I would prefer the lowest frequency (at same overall db level) as it sounds least like anything ”popping/snapping” that draws attention.

Just don't ask me to try the .22 Belita on my .30 Impact. :)
