Just my opinion but, I'd stear clear of the Smith, they still make a great revolver but their semi-auto leaves alot to be desired. Their customer service (to use the term loosely) is getting worse and worse. I've owned a 100 prior to buying my Beretta and can say the quality of the Taurus is every bit as good as Beretta. HTH
How often are you planning on shooting your pistol? Less than 500 rounds for it's entire life? If so, the Taurus might be an okay pick over the S&W, but that's is only if you will save alot of $ by opting for the Taurus.
There is nothing wrong with the S&W M&P pistols. They are quality products at affordable prices. They are gaining huge ground in the Law Enforcement market, stripping away what was traditionally Glock territory.
And no, Taurus is not the same quality of Beretta. Ever heard of a police department or government agency in the U.S. that issues Taurus firearms?
