Montado grips

[Yakima Red]

Even'in. Several years ago I bought a pair of TALO Montado's. I took them to the range, shot a full cylinder in each, cleaned them and put them away. They have not been out since. The grips are way too small for my hands. I don't have big hands, just long fingers. I'm looking for a little bit bigger grips. Looking for suggestions. Thanky kindly.

If you look on Gunbroker there is a grip maker that makes extended grips.

You need to clarify what you mean by "bigger."  Do you mean thicker, longer or both?
