I own one in .40 cal and I also owned a 24/7 in 9mm. I can honestly say that I have never had a problem with the millenium. And funny enough the 24/7 was a great shooting and accurate gun. I dont really remember now why I got rid of it, but it wasnt because it wasnt a good gun.
As for the .40 millenium, I have never had any issues with it, but with that said I dont care for the trigger pull and it is slightly bigger than my Glock 27 so I always end up carrying the glock instead. Also, the taurus' although I like their newer guns, are always hard to sell if you ever need to sell it. But over all I think they are good guns. I know most wont agree with me but I dont how much of their opinion is based on life experience. If it is what you can afford, then go for it !! Its better than being un armed!
