Don't do it.
I had three, all three eventually developed problems.
My "pard" had two, both developed problems.
Taurus developed that gun to get into the CAS market but it's just not solid enough for such heavy use.
There's a laundry list of issues that folks have had but the worst are that the springs get weak fast and the transfer bars aren't always machined right causing light strikes and even worse they have a bad habit of developing nasty "trigger slap" which stings like hell and eventually breaks parts.
I loved the way mine felt, looked, and handled, but the functionality was a nightmare.
