I've already said "send it back", so we'll leave that one.

I own a GP100 in .22 and in .357. Went by my LGS, and they have the 617 in two sizes on sale, so had to fondle them. But I was disappointed in the finishing. It was inconsistent, and comparing the two, the Ruger on their shelf appears cleaner and brighter than the 617 just to start. Barrel was straight, action worked, and I am still considering the purchase, but I see a lot of work to bring the finish up to par (lots of scratches and buffing marks in the SS finish).

I am still considering one based on the price.
