Great looking 41 Spl Sugar River. My GP100 was manufactured in Oct 2010 with the Hogue grips. I purchased the old style 2 piece and the grip locator had to be driven in with a leather mallot. The sides of the rubber fit flush all the way around but the wood inserts stick out as I said about 1/16". Plus it was inletted where the hammer pivot pen is located. I had to fill this in as the pivot pen would work it's way out after about a dozen times of dry fire. Maybe these grips just weren't ment for this gun. Fortunately it's a 327 Fed so not so much recoil that would cause a problem with the grips not fitting quite as they were intended.
