A Model 240 is a semi auto. I've never seen one in person but from the looks of the photos, that magazine it will hold more then 2 rounds. I suspect it's been "plugged" if that's all the shells you can get into it. (or something's wrong with the magazine) When hunting migratory waterfoul in the US, your shotgun must be capable of holding no more than three shells. The end of the magazine should unscrew and if you open it you should find a spring and a wooden rod. Leave the rod out when you put it back together and you should be able to load four or five shells in the magazine to hunt upland game. But remember to put it back before duck season.
It can, but, damage will eventually happen. Not recommended.
Mossberg DID make the western field m172a. Western field is just a hardware store brand name, the same as Sears had alot of firearms made by Winchester, High Standard, Mossberg etc.... under the name of Ted Williams, JC Higgins, etc...

Your Western Field shotgun has a value of between 35-90 dollars.
A single shot pistol, a Derringer and even a revolver are technically NOT considered semiautomatic. To be semiautomatic, the weapon would need to use the energy from a previous round to cycle the action. Revolvers use the muscle energy of the shooter's finger to revolved the chamber.

There is a tube extension for a Winchester Defender 1100. Extensions include a 7 shot, 8 shot, and a 10 shot.
If it was manufactured prior to 1968 it probably doesn't have one.
I paid $59.00 at Cabellas for my son's.
