RE: Taurus model 66 .357 vs. S&W model 620
I have a Stainless Taurus model 66 .357
I love it. I have never had any accuracy problems, andI'll admit, I've not treated it the best. I bought it for carrying around the woods in all types of conditions and climates and I just bring it in, wipe it off and it will always perform the next time.
I'd probably tend to agree with the fact that a S&W is a better built, better made firearm than a Taurus, but IMO not so much better that I'llspend $200 or more on one. I don't compete with my hand guns and if you do, again IMO, that would be the only competetive advantage S&W has over Taurus. But for pleasure shooters,and successful hunters I don't think you'll notice an accuracy OR dependability difference.
Good luck!
