Yeah FROM reading other peoples posts I think it's a weak point on some pistols she told me I also needed the spring to. Go with it. I don't know for sure but she seemed familiar with the issue. I got the parts at no charge and that surprised me because about a Year ago I pulled the pistol down and polished all the trigger parts and lost a detent ball and when I called Taurus to get a new one they told me that I took the pistol apart way too far and voided the life time warranty. I just figured I'd have to pay for the parts but they shipped them free of charge
