Gee, and after all the crappy advice about Taurus. Perhaps they all missed the fact that you were shooting your re-loads, and that factory ammo worked fine in it. That is, after all Taurus fault, I'm sure.
The Taurus and the S&W are not the same in the crane/yoke design. When the two companies separated, Taurus did not get the patented improvements S&W called the Endurance Package so the Taurus crane assembly is more prone to have problems.
Where do the posters get this from. Bangor Punta owned S&W and Taurus for a short while. According to both S&W and Taurus, there was little, if any, transfer of technology between them. Sort of like saying that a Buick used technology from Pontiac in their engines in 1968. They were all owned by GM, but had their own engineering staffs and the engines weren't anything alike beyond the V-8 indicator.
I own 14 Taurus pistols and semi-autos. Some are approaching 25 years old. I actually shoot them regularly, not wax poetic over a safe queen S&W. I've used Customer Service once, when I deliberately shot a non +P rated Model 85 CH loose with a steady diet of +P and +P+ rounds. I sent it in, along with an explanation, and, in six weeks, had a rebuilt, and re-blued, revolver in my hands. FREE.
I also own S&W (broke on first shot Model 625-3), Sig (cracked the slide in less than 75 rounds P229), HK (shot 8" groups at 15 yds. until barrel replaced USP), Colt (Series 80 with rear sight dovetail cut way too wide to hold sight in place), SA (Loaded Model 1911 that wouldn't feed anything), and a host of rifles and shotguns that didn't perform as their Internet fan-boys assured everyone that they would.
Brand loyalty requires the reverse, that the Brand be worthy of loyalty. Constantly referring to Models built 20 years ago isn't loyalty, it's ignorance.
