As other have said, buying a shorter 'drop in barrel' [it won't be that easy] will require cutting down the stock and possibly refitting the ramrod tubes--then besides the extra expense of the new barrel, you'll still have the original long barrel which will be of no use to you anyway--so I'd either leave it alone or cut down the original barrel. Personally, I prefer the longer barrel in a squirrel rifle--the weight ain't that bad, helps shooting and has a better sighting plane. I thought I wanted a short barreled .32 once and had one built with a 36" barrel--I still have it, but regret the decision and wish it was 42". It is nice and light, though. I'd keep the Dixie as is or trade it as is and buy what you really want.
