I purchased a Hogue grip about 2 years ago for my 625 and it was exactly what I wanted in fit. Fast forward to month ago and I reordered the same item for my new 929. The new grip came in and while very nice it had a significantly different shape at the base. I contacted Hogue and they said they had changed the shape about a year ago. I explained I was disappointed given my past positive experience; I had reordered the exact same SKU expecting the same product. In the end they offered to remake me a new grip using the old one as the template if I sent them both. They said they there is variation given they are all hand finished and by send in the one I liked they could make an exact duplicate.
I was pretty impressed they were willing to remake the grip versus just telling to return the new one.
