I think the range loss is as it pertains to subsonic rounds, which also tend to be pushing heavier bullets than standard. Rounds like .45 ACP, which are naturally subsonic, would not be affected by such. It would also depend upon the construction of the silencer.
The one first-hand source I have was a roommate of mine at 24th ID, who was with 2nd Ranger BN before an injury. He told me that while an MP5SD is very quiet (the bolt clatter is MUCH louder than the firing noise), the range is degraded significantly over a standard MP5. This, he said, was primarily due to the shorter rifled length of the barrel and something having to do with gas coming from the baffles. Silencers with wipes also degrade range. Brian Roethel knew his weapons, and was armorer-qualified on weapons I hadn't even heard of at the time. Most research I've done backs this up.
