I installed a Plug in my 642 and think it looks fine. In the future, if I bought a S&W with the lock, I might just disable the lock by removing the nub that actuates it, and just leave the external part of the lock in place. The whole lock thing looks flimsy when you take it apart and I'd rather not have the potential for the revolver to malfunction.
