As effective as what they're attached to. To be completely suppressed, the projectile needs to be traveling at a subsonic velocity. The .45 ACP is a naturally subsonic round, as is the 9x17/.380 ACP. The .22 Long Rifle is borderline. Most cartridges are not, and require special loading to remain at subsonic velocities.
With a supersonic projectile, the sound will still be suppressed to some degree, but the crack of the projectile as it goes supersonic will be unavoidable.
Revolvers, contrary to what's shown in several Hollywood films (Desperado is one which comes to mind), cannot be effectively silenced. The gap between the cylinder and the frame allows for the escape of gases (and, consequentially, sound).
check with the prosecutor's office
Unfortunately yes. But there are ways around it.
if a gun has a threaded barrel, (required for a silencer) it is classified as an "assault weapon" and is illegal in California.
Yes, provided you have complied with the FEDERAL law regarding suppressors. This is governed by 18 PA.C.S.§ 908.
No, you have to have a tax stamp from the ATF... but with that stamp it is 100% legal.

Because they could easily be used as firearm silencers.
