gasaman, your gun is worth more and harder to find than his. But he's a gun dealer, he can't stay in business making trades of equal value. I'm not trying to rip on him, that's just the way it is. Based on what I see that actually sold on GB, I would buy that gun, and then sell yours. I'd put $1300 on it. After all is said and done, you would have a couple of hundred to buy ammo.
BTW… you are paying a premium for a no dash Pre-Lock. If you just want a range toy or a home defense revolver, buy a new 686 for $900. You are getting the most popular revolver made and you aren’t buying someone else’s problem.
