Be careful when you order grips for your Vaquero. You don't have a NM Vaquero, you have a large frame original Vaquero. And you don't want to confuse someone into thinking that you want grips for a New Vaquero, because they take different size grips.
Your grip frame measures 1/2" thick and uses XR3-RED size grips, and you can measure it to confirm.
The mid-frame New Vaquero grip frame measures only 7/16" thick and uses XR3 size grips, which will not fit your gun.
It's a good thing you don't like Altamont grips, they usually do not fit well. I also recommend Carl of Private's Custom Grips as a good way to go.
NOTE: if you follow Private's instructions and photos for assembling the grip frame, recognize that the hammer spring and strut assembly is shown backwards; do not install as shown.
Jim, thank you for the heads up. You are correct I do not have a NM. I have been talking with Chad at Chigs Grips and he helped me figure this out. I placed and order for English Walnut Satin finish grips with Chad at Chigs Grips. He was great to talk to and was very responsive to my questions.
