Well, even for a Taurus, I'll take a different tack.
Have you had anyone else shoot the gun? How does it do from a rest? What ammo are you using and have you changed to another weight bullet or brand.
IMO - I need to start with the "software" before I start fixing the gun. 99.7 percent of the time it is usually - not always - the shooter.
It may be that you and the gun don't get along.
If the gun misbehaves for multiple shooters then I'd start looking at the gun.
