I'm in the same boat. I love shooting suppressed and the .45's are so much nicer suppressed. But I'm not paying the stamp and jumping through the hoops.I've shot suppressed before and yes, it's interesting and fun. But unless/until they are removed from NFA I have no interest in going through all the legal "hoops" and expense of registering one. They shouldn't even be this controlled and since the last several SCOTUS decisions I don't get why (legally) they still are since they are in "common use" with a couple million of them owned.
And how are they even considered dangerous destructive devices? They have no moving parts, don't explode and cannot harm anyone. In Europe, if you hunt without one you are considered rude and inconsiderate.
