I have a Stevens 820B model and I shoot mine. Picked it up about 30 years ago, used....with the previous owner leaving but about 18 1/2" of barrel on it.
It has no trigger disconnect....meaning, if you simply hold the trigger back, every time you push the slide back into battery, it will shoot the shell. As fast as you can cycle the action, you will fire a round....without ever having to move your trigger finger. Great for folks with poor hand coordination issues.
Mine sports a bayonet....the result of the gunsmith providing some OJT for me one late evening after we closed the shop. Hey, you gotta learn to sliver solder at some point in time.
