The price is not much cheaper than the Uberti, so price has nothing to do with anything. The 4 inch barreled guns don't produce much usable power for wacking bushy tails or a rabbit that hopped off and stopped at 20 yards to look back. The added inch and a half should be good for quite a bit more velocity and power over the shorter 4 inch barrel. That doesn't help anything if the gun is so sloppy you can't hit anything with it.
A friend gave me a CVA kit gun that was never assembled all the way. I am considering sleeving it to a caliber that will allow me to use the same 000 buckshot I use in the 36 rifle. That project will be a while getting completed.
Anyway, you all have a nice day!
