I just put a Houge Taurus tracker grip on my Poly Judge. They say it won't fit but with a 4mm x.7 x 40mm screw it fits just fine. It's really easier to hold onto now.
Glad that works out for you. My wife has a Tracker in 44 Mag, and the Hogue grip is a whole world better than the factory grip that Taurus ships their guns with.
