So I purchased my first can, an AAC 7.62 SD-n6. Sending off paperwork tomorrow. When I picked up my paperwork I figured I'd just go ahead and buy a can for the pistols too so I could get them back at the same time as the current wait on paper for individual is 8 months. Only thing they had in stock that covered 45 and 9mm was the new Sig SRD45. I was more interested in the AAC ti rant 45 for less money but they had to order it. So I said ok, I'll pay for it and you go ahead and order it. They said 8 weeks to get it in. So I asked if they could call and get the serial number so we could get the paperwork done and sent off while waiting for the class 3 dealer to receive it. They said they couldn't do that. I've read several places where folks have done that. Not sure why they wouldn't do that for me. I went ahead and paid and ordered it but have any of you all got a serial for an "on order" suppressor to shorten the wait time?
