I just got a shipping notification from Summit today on one of these.
I will say I was a bit disappointed with Summit's customer service - I sent an email, called several times (within their window) and texted. The only word I got back was a text saying that they had more than one available. I really would have liked to hear a bit regarding the condition and maybe gotten some photos like I had requested.
But, alas, I figure this has to be about the last batch of 4006's that we will see, and I know I've missed out on some surplus guns that I later couldn't touch for a decent price.
I'll happily report back with how it compares to my "VJB" 4006 and ex-Brinks 4046. At the end of the day, these 3rd Gens are still head and shoulders above anything new you can buy at that price point.
Now if I only I had picked up a CHP 4006 back when I could..
