After reading all the discussions here, it looks as though I'm better off if I wait and find a pre-lock model. It may be a while though, cause like I said earlier, that is the first used 686 I've seen in over a year. Luckily though, there's no rush.
I have seen some on gunbroker, but I've never purchased a firearm online and I'm a little hesitant to buy one without first looking at it myself. If it were NIB, I wouldn't mind. But buying used, online, makes me a little nervous.
I appreciate everyones input and opinions. Thank you!
