I bought my first 1897 back when I was around 20, long before CAS made them "cool". Nobody wanted them. It's a 1913 manufactured full choke takedown that someone had chopped back to 25". I spent many years shooting skeet and sporting clays with it. Before I found Modern (Wobble) Skeet, shooting 100 straight was a boring, weekly occurrence. Modern Skeet is a little more challenging. It's usually 22-24 for me now.
I'm hooked on the 1897 shotguns and now have 7 of them, ranging from 18-1/2" to 32". One is a factory "Brush Gun", solid frame, 4-shot magazine tube, 25" Cylinder Bore manufactured in 1898. That was my 1st anniversary present from my wife.
After all these decades of shooting the 1897 I decided to modernize and started looking for a good shooter grade Model 12. I ended up buying two of them the next gunshow. I won't chop down an original gun. There's too much of that going on already. I have a nice 30" full choke and found one that someone already butchered by installing a Polychoke. That one is now 18-1/2". As much as I try to like the Model 12, it just doesn't fit me as well as the 1897 does. Maybe it's because of the many thousands of rounds I've put through the 1897, but the Model 12 just doesn't do it for me.
