Will the Pachmayr Decelerator grips fit a Taurus 66?

Pachmayr used to make a grip for the Taurus M66. I'd call them direct to be sure that the grips would fit the gun. A tip, have the gun in front of you when you call. That way if they have any questions about the gun that might affect the model of grip you are ready to answer them.

Usually the two companies grips aren't compatible due to screw locations.

Thanks for the reply. You were right about the screw locations. After shooting it some more, I am just going to stick with the factory grips, for now.

The pachmayr site specifies that the decelerator fits taurus large frames. The Hogue site states that the same grip fits the medium and large frame square butt.
You might want to check some more, but I read this to mean that the medium and large frame taurus revolvers use the same grips.

The decelerator is the same as the gripper, but made of a softer rubber.
I use the gripper on my model 10 S&W and find it to be more than adequate, and I also have the Hogue but find the Pachmayr allows you to go higher on the backstrap and is much more comfortable.
Hope this helps.
