Go in a gun shop and buy a brand new gun with the stipulation you can take it home and within three days if you don’t like something about it you can return for full refund . Then think about a three day policy where you cannot fire it but you can return for full refund except the shipping when it’s an online transaction for a previously owned gun . Some of you wanna buy with zero risk for you , why not just ask the seller to give you the gun to get it off his hands
