Dropping the Mag on every shot???
Take a look at the mag release button, you might have some dirt preventing it from returning to the locked position, no luck there try another magazine....
Taurus made a poor product in the early days, but wisened up in the early 1980's I was hard pressed to Buy S&W when I compared the copy-cat Taurus models. I was a Dealer at the time, recommended and sold Taurus 3 to 1 over S&W. Sorry,,,, I just thought it was a superior product with a better Warranty. My customers agreed...
It's entirely possible that they fell back into the quality slump.
