My brother has the 740, he bought it as a slim line replacement for the Glock 27. He had a few failure to feed problems, and hated the trigger so I think he is going to trade it in if he has not already. Taurus semi autos are notorious for terrible trigger pull, and I don't know of any aftermarket fixes for any of them. About the best bet you'll have is to find a good smith willing to smooth out and lighten the trigger for her.
