I thought this was an interesting pistol, and I'm buying it. Until I saw this, I thought that a 686 was pretty much guaranteed a full underlug. The seller swears it's not just a 5 inch 620, but a half lug 5 inch 686. Can anyone tell me more about the half lug 686?
It's interesting that Smith & Wesson latched on to the term "half lug barrel". Smith originally termed this a "heavy barrel" such as that on the original .44 Magnum and 1955 Target .45. This would be as opposed to the standard tapered barrel on say the .357 Magnum. Then again, their marketing folks came up with "crush fit" barrel fitting which is really just standard fitting less the pin.
