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.
An Internet forum is like having a friendly conversation over a drink at a local tavern.
Some guy at the end of the bar always has to stand up and shout something that makes no sense at all.
