So after an 11 month wait I got the call today to go pick up my suppressor. I want to put it on my 9mm carbine so I ordered a spacer to replace the spring in the suppressor. What would happen if I didn't know any better and used it on the carbine with the spring instead of the spacer?
 
Personally I wouldn't shoot a pistol can on a fixed barrel without replacing the spring with a fixed barrel spacer. If you're not familiar with what that spring does (or how a Neilsen Device/Booster works on a suppressor) this video is a pretty good illustration:



The booster decouples the suppressor from the barrel by extending the can outwards for a split second. This allows a recoil operated tilting barreled firearm (like a glock or most other semi-auto handguns) to unlock without having to deal with the additional weight of the can hanging off of the end of the barrel.

On a fixed barrel, the booster will just jack-hammer your can back and forth against the muzzle, potentially damaging your muzzle threads and/or the piston at some point.
