J&G shipped fast!
I ordered a used S&W 67 from J&G Sales last Wednesday, March 24th. They emailed me the next (Thursday) night saying the gun had been shipped to my local gun store. The gun store called me on Saturday to tell me it had come in.
I haven't gone to pick it up yet, but when I do, I'll come back and post further.
That's pretty fast service! Kudos to J&G. Now if the gun is in good shape, I'll be completely satisfied.
