Being a big fan of single shot weapons, here recently I have become intrigued by the shotgun/rifle combo guns. After doing a little research I see there are many options and combinations. Some have interchangeable barrels, some are over/under (which I like), and insert barrels are also available to add a third caliber such as .22...My interest is a survival/hunting/last ditch effort self defense rig...I think I pretty much covered every aspect of a firearm with those interests, besides fun shooting, so I'll add that reason as well. Does anyone have combos and what are your experiences with these? Recommendations? Which ones to stay away from? Any input is appreciated. Pics are always a nice addition. Thanks for any input you may have.
