Do you have a link to "like this" ?
I have a .40S&W PT24/7 PRO DS LS (Long Slide and same size as OSS) I expect uses same recoil spring assembly. My spare is about 4-5/16 OAL encapsulated or contained one piece assembly that consist of 3 pcs - spring, rod and cap button screw (referring to muzzle end button). OSS also shows in manual a morph assembly mad up of more pieces, but would think a single assembly would work ok.
Your chances of getting anything parts wise from Taurus are zero as this pistol is on the list of recalled Taurus. If you're not aware of the lawsuit, just do some browsing here or on line about recall or lawsuit. Taurus has no replacement for your pistol and no parts to repair that they would sell. And no, I'm not interested in selling my spare. I can shoot a pic of it I you need one to compare with a replacement.
