I have had a couple Taurus Revolvers for many years.A Raging Bull 44mag,and a Tracker 22lr,and have never had any issues other than some timing problems on the Tracker.My cousin has a Tracker 357mag,and has never had any problems with it.
Taurus has had several problems with a few models,but every other gun manufacturer also has problems with many gun models also.
Everyone of them are making products as cheap as they can get away with,and sometimes one's with defects get out into the public's hands.The same goes for all of the Ammo manufacturer's,their making most of their ammo just as cheap and skimping on the Q.C. time.
I hate to here that a firearm blew up and someone gets hurt,but in today's tough economic times,it's bound to happen more often.Quality products are hard to find anymore.
