How funny! I distinctly recall back when the L-frames first came out. All of us "gun nuts" were contacting every gun dealer we knew, looking for a 586 or 686 and wanting to trade a 66 for it, too. Here we are, what is it, 30+ years later, and folks are trading back. (Maybe now that we're older, that extra few ounces of steel in the slightly bigger frame is just too much for the old bones to carry?)
Anyway: the ebb and flow of the gun world. Just jump in and let the current take you wherever it will.
Oh, and I think you did good, t4.
