Looking at getting a suppressor. I see the Missouri process on a few websites that sell them. But, is there anything 'heads up' I should know about? I know it'll take a while to get thru the bureaucracy...
You can do it as a personal purchase or as a trust. It's pretty straight forward, just a long wait.

What Rich said. If this is your only NFA item you should use a personal sale. If your interested in getting other items in the future a trust may serve you better. Just my opinion!
