Jimmy, are you looking for a hammer shotgun or hammerless? As was mentioned earlier, Stoeger makes a good one at a very reasonable price. I had one and really enjoyed it, but my daughter wanted it so I gave it to her.
I currently have a CZ hammer gun and am completely sold on it. Excellent quality, but as Gunhacker mentioned, they're a little pricey. Fortunately, I got mine used so it wasn't so bad.
I had an old Fox B in 16 gauge years ago. Cut the barrels down to 19 inches, just so there wouldn't be any question as to the legal length. But, alas, like my Stoeger, one of my sons liked it a lot, so he's got it now.
Finally, I got hold of an old A.H. Fox Sterlingworth. I had the barrels cut down and used that for years in Cowboy Action Shooting.
So, that's another option for you, Jimmy. Find an old used side-by-side and have the barrels cut down.
Anyway, here's a picture of the two I currently have. The A.H. Fox on top and the CZ hammer gun on the bottom. Good luck in your search.
