I am slowly getting back into shooting revolvers after a long absence, and am working on a servicable battery. I currently have a J frame airweight snubby and L frame 4". I am looking for something in between, able to do double duty as carry gun and still enjoyable to shoot. I was thinking a 13 or 65 in 3" might be a good compromise, but they seem pretty hard to find. Any other suggestions for a good in between model without the internal lock?
