I agree with Wil Terry and sp327. The last three new Ruger SAs that I ordered had quality control issues, two of which were issues with the gripframe. All three guns were distributor exclusives, which I would have expected to be of higher quality. The gripframe problems seem to be especially bad on stainless guns. I will no longer buy a new Ruger off the internet unless I first see pictures of the actual gun that I am buying. I still think they make great guns.....I just want to look at mine before I commit to buy it.
As far as Altamont goes, I have ordered dozens of their grips over the past few years for Ruger, Smith, and Colt revolvers. I find them to be of high quality for the price, and have not had any issues with them.
