Have it examined by a gunsmith.
Yes
The Stevens 59A can shoot all size loads from #12 to slug. So in short, yes.
Do you mean "Shotgun"? Stevens didnt make a shotgun model 44. Perhaps it's a rifle? Stevens made a Model 44 single shot Rifle valued from $250 to $600 in mint condition depending on caliber.
No.
Yes, you can shoot slugs out of a Stevens Model 107B 16-gauge shotgun, provided the shotgun has a smoothbore barrel and is in good condition. It's important to ensure that the slugs used are compatible with the shotgun’s chamber and bore specifications. Always consult the owner's manual and follow safety guidelines when using different types of ammunition.
A shotgun typically has a smooth bore and is designed to shoot multiple pellets or a single slug, while a rifle has a rifled barrel and is designed to shoot a single projectile with accuracy over longer distances.

Oh, dude, the Stevens 620 is a pump-action shotgun. So, like, you gotta pump the forend to chamber a round and then pull the trigger to shoot. It's not rocket science, just point and shoot, man.
Can't be answered without knowing what it is choked.
yes your Stevens shotgun should be safe to shoot,I'm not saying run nitro mags in it but it should function fine with high brass game loads.....they are a well built shotgun designed by John Browning..if your ever looking to sell it i'd be interested..........kyledeno@yahoo.com
Yes, you can shoot slugs in a Stevens 58D 20 gauge shotgun, provided that the shotgun is in good condition and you are using the appropriate type of slug. It's important to ensure the choke is compatible; a cylinder or improved cylinder choke is ideal for shooting slugs. Always check the manufacturer's recommendations and consult with a knowledgeable gunsmith if you're unsure.
