You got this from Norcross right? I bought one as well. It is a variant 4 (or 3 depending on the side of the decock)
It has no safety. Additionally that is a nickel-plated finish, not stainless, which is why they call it two toned. Sound about right?
I had to send mine back. It had a fracture in the slide at the rear and the finish was coming off. I was pretty unhappy after I discovered that. However, the owner of "Hit and Run," Phil, took good care of me and sent me back a full refund.
I'm now going to get a Brand New Usp .40 compact stainless. I will probably never buy used again. This just left a sour taste in my mouth
