I have 3 16 gauge shotguns; I like and use all three. The first one I owned was a Remington model 11. It originally came wiht 28" full choke barrel and I had the barrel cut down to 26" and added a poly choke. The gun has accompanied me on many trips and accounted for a lot of game.
The other guns are an Ithaca M37 pump with a 28" modified barrel; I bought a slug barrel with rifled sights to go with that one. Finally, I have a Stoeger Uplander shotgun with 26" barrels and IC/Mod chokes. I like taking that one to the pheasant preserves and into the grouse woods.
If you do get a 16 gauge, you might want to consider reloading for it.....16 gauge target shells are becoming scarcer and scarcer at the big box stores anymore.
