First off, let me say that I just found this forum. Stumbled across it while looking for information on shotguns and thought I might as well join. Looks like a lot of good information here. Next, I'm a pistol guy. I've carried handguns for years and thoroughly enjoy my 2nd amendment rights. I've never owned a long gun of any type, even though I fired them as a child while squirrel hunting with my father. Thus, my ignorance of shotguns in general, that will probably become apparent with my questions. I'm looking for a shotgun for home defense only. I'm sure I may some day take it hunting if we ever move a little farther out of the urban areas, but for now, it is strictly to allow me to better protect my family. Specifically, I want a shorter barreled gun, pump action, with both a pistol grip and a shoulder stock. 12 gauge seems to be the most recommended size for my purposes. Questions: (and thus showing my ignorance. I'm sure I could find this all out with a little searching of my own, but since I came upon this treasure trove of fellow 2nd amendment defenders, I thought maybe I could save myself some self educating) 1. What make/model of shotgun will meet my needs (and wants)? 2. Are there different types of shotgun ammo besides shot and slugs (these are the only 2 types I remember my dad using when I was little)? 3. What type of ammo would be best suited for my purposes? 4. I seem to remember coming across something about 3 inch and 3.5 inch shotgun ammo. What's the difference (besides length) and which would I want to use? 5. I would probably want to attach a tactical light to it. Any recommendations as to pros or cons of this, and will just any small (Surefire like) tac light work? Thanks for any help and information I receive on this. Hope you all have a wonderful Christmas!! Remember, He is the reason for the season!!
