S&W, Ruger, Taurus
In my younger days I used to work in a gun shop as a sales clerk, we always used to take trade-ins of used guns. To my recollection I've never seen a out of time Ruger during my few years at the gun shop, in fact I've never seen one period. Although I think the Smiths are durable (meaning I don't think a Smith barrel will wear out faster than a Ruger), I do feel the lock work is much stonger and durable on the Ruger. In all fairness to S&W, we used to get 10 trade- ins on Smiths to one of Ruger and the majority were K frames rather than L's, although I think the lockwork on K's and L's are similar.
