actually I'm not america and I don't live in america. I live in north europe.
The only reason I want a gun with a silencer and unmarked bullets is to have the ability to defend my self when ther are no more corners to hide to anymore. And to fuck someone up if he or she is asshole enough.
You are in Finland, correct? IIRC, suppressors are not an issue for you, they are just another shooting accessory. In the US, they are as regulated -- under the same statute and regulations -- as full-auto weapons. Our law givers are so idiotic that they believe the movies and that "silencers

) are magical evil devices and need the benevolent government to regulate.
I have to pay a $200 "transfer tax" on top of the cost to own one. PITA.
BTW, because you are allowed to do your own maintenance on your suppressor, an old-school "wipe" based suppressor is fine. You can even make your own wipes out of felt. In the US, cutting a circle of felt out while in possession of a wipe-based suppressor is a 10 year felony. Such is the idiocy of our government.
Do send a pic of the gun and I will tell you what to look for with wear and tear and help you decide whether or not the actual pistol is worth it.
