sorry it will not fit it is made to mount on a picatinny rail

Hi Wayne and welcome. No Sir, this is a Picatinny mount option only. For the Taurus TH9 you could use these : https://lakelinellc.com/red-dot-mount-plate-for-multiple-sights-fits-taurus-th9/ ---------------------------------------------------- budsgunshop.com/product_info.php/products_id/157015/truglo+red-dot+mcro+tru-tec+rib+rmr

That's a Big No. Optics like this are made specifically for a rifle with a piccatinny rail to attach to. The T.O.R.O Taurus is the Optics ready Taurus, not this model.

Hi Wayne, no sir, this is made to mount on a picatinny rail. Also, the Taurus TH9 is not optics ready.
Stay safe & have a great day!
