Look for a reputable local gun store, or pawn shop (yes some are reputable) that deals in used firearms.
Broken parts, that can be an issue with decades-old or antique guns but with modern handguns if there's something busted you'll know it and if it doesn't shoot you can bring it back to show them.
If seeking used firearms online auction such as Gunbroker be certain to deal with sellers that have perfect 100% user ratings (browse each seller's recent transactions to read feedback prior to bidding or buying); most good sellers will stand behind what they sell or if it was not represented correctly. Also be sure when buying/bidding online to only deal with auctions that have ample photographs and thorough description of the gun and its condition. Ask simple, brief questions about
>rust or pitting
>condition of bore
>cracks/warping in wood stock
etc. if it's not already clearly shown or described in the online listing or pictures.
