In Texas as long as you are a individual and not a dealer there are no regulations for FTF gun sales. There is no duty on your part to check out the buyer or anything else.
I generally will only sell to CCL's, or someone I know, but I always ask for Identification when we meet. Once I see that they are legit, I will show them my CCL so that they know I'm on the up and up. Never invite them to your home or go to theirs unless you know them really well. I always like to meet in a neutral area, but "not" a loney back road and I always carry.I have not sold a firearm in a number of years but have recently considered doing so would like boards members tell me how they handle FTF sales, do you request ID or what steps necessary to protect myself.
