It's a nutted barrel, so just about anyone who does barrels will do that. I had McGowen do a barrel for one of my 99s and was very happy with the results.
As far as the stock goes, the 110 is a common model that has been in production for a long time, so there's quite a few aftermarket stocks out there. That's really just a matter of preference. If you're just looking for something cheap and functional, Hogues are pretty easy to come by... they are definitely not works of art, though.
