I ordered a laser / light that works on a rail and supposedly fits my Taurus TX 22s. Streamlight 69245 TLR-4G 160-Lumen Compact Rail Mounted Tactical Weapon Light with Integrated Green Aiming Laser. I have just the light on another TX22 and its really nice. So I hope this one holds up. If anyone knows how these are please chime in and let me know either way.
