There is absolutely no legal liability, neither criminal nor civil, for using a legally
suppressed weapon in a legitimate case of s.d. The D.A. won't
prosecute you, nor, if you're living in a "REAL" state, will you be subject to civil litigation.
The silliness about what kind of weapon you use for s.d. being relevant in a legitimate case of s.d. is just too sophomoric for further comment on my part.
