My wife has been wanting a new Glock for some time now. Recently I found a Gen 3 Glock 19 with a pink frame and black slide online. I went to the LGS who does transfers and was told I needed to check the SKU on the California Handgun Roster before I could have it shipped here.  When I look at the roster it doesn't list an SKU for the Glocks. It has a listing Glock 19 OD/ polymer,steel, and one that says Glock 19 /polymer, steel. I notice that some of the S&W's list an SKU. How can I find out if this gun is legal in CA? Any help would be appreciated.

Check the roster, gen3 should be legal.

I'm far from an expert, but to my knowledge Glock doesn't make a pink gun. It sounds like the gun you're looking at online has had some custom work done, which is why you're not seeing it specified on the roster.
