you will like the 28 gauge buddy, quite a few here have them and the concensus is they hit almost like a 20 gauge and recoil just a tiny bit more than a .410. A great gun for your needs of squirrels and quail. Slugs for the 28 have been mentioned by several here but I am not aware of anyone (company) who is making them at this time. Some here have spoken of reloading slugs for the 28 gauge, perhpas they will speak up...<><....
and by the way, welcome aboard and nice to have you here with us. Come often and stay late, for when your here you are among friends...
