Is there any performance differences between double action revolvers with a full lug vs. half lug vs. no lug? Is it just looks or is it all about the weight added to the barrel? Or does it have to do with adding strength to the gun somehow? Please school me on this one. I'm learning tons on this great sight! You guys are a genuine wealth of valuable information to a revolver aficionado like me! Thanks million and please keep it up!
