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 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.
Pappy, i attended the san Antonio gun show yesterday in a new location and it was terrible, not a lot of stock, very poor selection, I had one hand gun to sell dealers wanted to give me 40% of value, all in all gun shows in the past 7-8 years have went down hill in our area.
