Well the craftsmanship/attention to detail, or qualitiy control may not be to the same level. But their engineering and technology has definitely improved.
Better metals are now available ( yes they may use MIM parts, but they work and they are getting better with time and improved tec)and a better cylinder lockup method which lead the ability to use a beefier forcing cone may indeed mean that it is a better weapon. Sure it's not the same to purists because it's got the "zit" or Mim parts , but from a design aspect I feel it's been improved.
However when listening to his opinion. Keep in mind that he is sponsored by SW and in the first few lines Jerry admits that he is a revolver guy,does it for a living, and SW sends him revolvers to shoot. So...even though he is a freak of nature when it comes to shooting, it doesn't mean he has an unbiased opinion in regards to SW
