I have become convinced that the frame-mounted firing pin, rather than the older hammer-mounted type is the source of unreliability in these newer guns. The lock bothers many on principal alone, but again it can be dealt with and so doesn't bother me as much. I have a TR 21-4 that I had a few FTFs with; I replaced the firing pin, but shouldn't have had to. I would just as soon trust my life to a 1917, as a post-2001 gun. The whole point of a revolver is simplicity and reliabilty. The workmanship seems to be questionable these days. A valid point about a 1950-60s gun being easier to work on and having better steel than a pre-war gun, but good luck finding one and you'd still have to hack it up for a 4"er! That's why jovinos are in such demand. Mine should have gone out for re-finishing this week. It has taken longer than anticipated.
