For the most part, if you can afford to shoot enough ammo thru a modern revolver meant for the cartridge shot in it, to cause enough forcing cone erosion that the gun is useless, you can afford to replace or repair it. Buy a new S&W or other revolver with a lifetime warranty and the gun will be fixed or replaced for free.
IOWs...not really as issue with today's modern revolvers.
Hmmmmm, most of my Smiths already have several thousand rounds thru them....several almost @ the 10,000 mark and none have excessive forcing cone/top strap erosion to prevent me shooting them. By the time I get another 10,000 rounds thru them and there is, S&W will probably be caught up. Sorry Taurus.
