Called the gun makers customer service and asked if I was able to, and they said I was not if it was used but "Only way I know it's used is if you tell me"...at that point I thanked him and just hung up. Unsure if I should follow through with registering it now as I have no idea if my number will be documented or what. Also, the only "sell" date I have is the date I bought it from another user on here, who bought it off someone else. The guy I got it from says neither of them registered it, but unsure if I shot myself in the foot...figuratively speaking. Anyone else able to offer up some experiences that might be similar to my own?
