If you are still interested in selling the gun, list it on a local for sale website in the for sale section. I live in Arkansas also, and there is a new website that is getting off the ground.
www.arguntrader.com This is for arkansas residents only. List it there as a for sale listing, and you can even throw some trade options too.
www.armslist.com A second site to list on. This one is nationwide, but the same sort of deal.
the good thing about selling from one individual to another individual in Arkansas, is that it is perfectly legal to do a "Face-to-face" or FTF transaction with another legal arkansas resident.
I have bought firearms from people on both of these websites. Since you are dealing face to face, you don't have to worry about shipping the gun, accepting payment, FFLs, etc.
Hope all goes well for you!
BTW, what would you want for the pistol? Maybe I need it! LOL
