That pic doesn't say "Made in Miami" it just says Taurus Inc. Miami, FL.
The gun is made in Brazil. Taurus Intl. is out of Miami.
Edited to add:
The other side of the gun will say
From Taurus' website:
The next milestone for Taurus came in 1982. This is when the Brazil management decided to "take the bull by the horns" by opening an affiliated company, Taurus, in Miami, Florida.
