I picked up a S&W Model 629 4" .44 mag for $299 a couple of years back. The previous owner shot about 12 rounds through it and pu$$ed out. Traded it in and gave me a great opportunity. Some times people bite off more than they can chew.While there's nothing wrong per se with a like new firearm, it would make me wonder,especially on an handgun, why somebody got rid of it that quick. Does it have a nasty habit of malfunctioning? Unless you're offered a hellova deal, wayy below new price, I would recommend sticking with actual new firearms. This really comes into play (for me anyway) with centerfire rifles as I'm a FIRM believer in properly breaking in the barrel-especially on factory level barrels. Bottom line is if they give it a cleaning, you cannot tell if just a few rounds have been fired through an semi-auto. Revolvers will exhibit lines on the cylinder from being rotated, and cylinder face/bottom of topstrap may be stained as well.
