Cmichael, not familiar with the Persuader. Is it a short barrel (18"?)
Anyway, to answer an earlier question a different way...
Slugs essentially turn your shotgun into a rifle. When you shoot a slug, you are shooting a single projectile, like a rifle does.
There are two kinds of slugs: rifled slugs (aka Brenneke's) and saboted slugs. You can shoot rifled slugs in your smoothbore barrel (no rifling). If you want to shoot saboted slugs, you'll need to get a new rifled barrel. It takes seconds to install a new barrel.
If you want to shoot slugs well, you really need better sights than the dot on the end of the barrel. However, that may work in an emergency. The only way to know is to shoot some slugs and see where they hit, with respect to where you aim.
Slugs are NOT for shooting birds or clay pigeons or squirrels or any of the things shotguns are traditionally used for.
BTW, we might as well clue you in on how to select shotgun shells. There are many kinds. Two items to be aware of are shot size (the size of the "bbs" in the shot shell) and powder charge.
Shot size is usually 8, 7.5, 6, 4, 2, 0, 00, etc. Bigger numbers means smaller bb's. Counter-intuitive.
Powder charge is usually stated in "drams" or "drams equiv" bigger number means more powder means more power and more recoil.
For shooting trap, skeet, sporting clays or any of the other "shotgun games" you will generally want smaller shot size (7.5 or 8) and smaller powder charge (2.5 drams or so?) No need beating up your shoulder. Smaller shot (bbs) means more of them in the shell, and denser patterns (more bb's per sq. in. of the circular pattern the shot makes).
Same is true for hunting small birds (dove, quail).
These are also excellent choices for home defense at distances under 10 yards or so. from 10 yards to 25 yards, you would want buckshot (0, 00 or 000).
For ranges beyond 25 yards, you are back to slugs and shooting rifle-style.
For shooting bigger birds (partridge, pheasant), you want bigger shot (size 6 or so).
I hope this is not confusing...
