Crimson Trace "Officers" length grips. The are the very best! You will need to order the longer screws and bushings, with the grips
An excellent product, I had the same set on a Sig 229 for 15 yrs! I currently have a set on a Commander. However I am keeping my Agents stock slim grips, as they are more concealable. The only draw back is your grip is going to be wider, more akin to standard grips then the factory slim grips.
