Cons: extra weight at the muzzle, extra length, if shooting a lot they get hot and can cause mirage which effects sight through your scope (only really an issue at the range).
Probably not as common in the states because their laws require a tax stamp application of some kind (don't really know the in's and outs of that) which can take over a year to come through before they can purchase a suppressor - they are gaining more popularity though. In some countries they are banned - most likely due to the the uneducated learning about them from movies where they are for sneaking assassinations... We can readily purchase these in NZ under a standard firearms licence (as you should be able to) and the benefits are great.
