I've not had to do any Extractor Work to the TriStar Pistols, but then again, I only have one, a T120.
I have replaced Extractor Springs on a number of Cz75's and Tanfoglio Pistols with the Wolff Extra Power Extractor Springs.
Those Springs do come a bit over=sized so they can be used in the Cz97B's as well.
In the Cz75's and Tanfoglio based Pistols, I did have to trim one coil, for proper fit and function.
Not a fan of Tula Ammunition here, but it probably beats throwing rocks with a slingshot.
