Who (locally) will you be ordering through or who will be doing your transfers? If figure not all of us here know of a nearby C2/3 SOT, so maybe a list of dealers across MO would help folks get started with their suppressor purchases. Also if you know of a dealer who stocks particular brands or models, that info will be helpful as well. If you're a MO dealer and will be ordering suppressors or transfering them, list your contact info, as well as brands you will sell.
Ideally it would be nice to find what I'm looking for locally, but that's not likely to happen. The second best option would be to have a local dealer order what I need, but again, that means finding a local C2/3 SOT, who is willing to do the order, and can actually get me what I want. Last case option I suppose would be to find what I want out of state, and find a local C2/3 for the transfer. But then I'm at the mercy of their transfer fee.
www.csmetall-werkes.com/ in St. Charles is the only place I've dealt with in my area which regularly has title II goodies. I haven't been there in a while, because of their weird hours (Fridays and Saturdays only IIRC) , but I assume they will be selling suppressors. They are a bit pricey, or at least that was my impression when I purchased from them in the past. Did an out of state SBR transfer through them years ago, and IIRC it was $50, but I think that went up a lot since then. Not sure what brands of suppressors they will deal in.
Personally, I'm not buying anything right away, since I have too many projects going. I'm eventually thinking of going for a KAC NT4 (probably be a bit difficult to find) and perhaps a SWR Trident to start with.
