SU,
I was waiting for NRA to contact me. I guess we were waiting on each other.
As for the Cheatham County Sheriff, there's not much to report. My customer was afraid that if I pushed the issue, the Sheriff would know it was because of him, and it could have repurcussions on the customer. Also, I couldn't figure out how the AG could word an opinion any clearer than TCA 39-17-1361 already states the law. It seems cut and dry to me, if the Sheriff and ADA can't figure it out already, what would it take to get them to change their minds.
I did hear, from another customer, that the Sheriff signed his Form 1 for an SBR, but wouldn't sign his Form 1 for a suppressor. I also heard that the Sheriff declined a Form 4 for a suppressor, which was presented to him by an attorney. The individual who told me this said that the attorney was considering suing the Sheriff, in order to compel him to sign.
As for Williamson County SRT, they actually have post-sample P90's with Gem-Tech suppressors.
