The Raven is a great little gun, but it should be shot to ensure reliability and then retired. The magazine springs aren't designed for extended use, but it's a fine little gun if you keep it loaded; however, if you load and unload it frequently, you may run into some trouble.
The gun definitely isn't worth a two-hour drive, though. If you're going to make the drive, you'd best fit in another purchase. The GP-100 is a great gun, but in a 6-inch configuration you'd be better off with a good used Security-Six. (I don't know why people like mid-weight .357s with all the weight in the barrel, but I'd pick a good Security-Six or S&W 66 if I wanted a gun that could pick up and follow a moving target.)
Getting back to the Ravens, most worked, but I'd try the gun before plunking down my money. Some had problems, and whenever I see used ones in great condition, I get a little suspicious. I have a Davis P32 that looks great and has the same design as the Raven. The trouble is, it won't eat more than three shots before jamming. I wouldn't sell it without full disclosure, but other people might. I'd hate to see you spend $72 plus $20 plus whatever transfer fees you have, only to end up with a klunker. Two magazines indicates they might have had a problem and tried to fix it by trying a new one. Just a thought.
Jennings J-22, a nice little pistol that works.
