Nothing odd about the barrel on this 627-0!!
This is the only kind of model info I care about if I'm considering a gun for purchase. As long as there are lots of nice, clear (in focus, please) photos - including one of the model number like this, then the ad really doesn't have to say very much else, except for the price.
That is what happens when I answer from a hotel while on the road. I get things confused sometimes. I clearly remembered the non fluted cylinder and thought it had that new flat sided, comp style barrel.
i'm not exactly an expert, but i prefer the "no dash" added on. If someone tells me they have a model 29 for sale, am i to assume it's a no dash? Could be a big, and expensive, mistake. I've inquired about a few guns on gb where it was listed as a simple model number. When i asked if it was a no dash, i was told it was a -3, -7, whatever. Imho, no-dash is good. It tells me just what it is, instead of leaving me to assume. And we all know what happens when we assume! +1 for no dash!
