Another advantage of the Model 37 is that it's ambidextrous, with the live shells going in and the fired cases going out the bottom of the action. It is a John Browning invention, originally built by Remington as the Model 17 and presently manufactured by Browning as the BPS. I have used more than one for years.

However, I have to make a pitch for the Winchester Model 12, with its voluminous magazine capacity and its lack of a trigger disconnect. Just pull the trigger once, hold it back, and work the slide, the gun will fire every time the bolt closes. Every other slide action shotgun I am aware of requires the trigger to be released and pulled for each shot.
