File under the heading that if it ain't broke don't fix it.
You will gain little if anything in handling. You will lose magazine capacity, balance and increase muzzle blast considerably. You also lose sight radius...and maybe some small bit of accuracy.
PS: I have a Trapper and have killed a ton of stuff with it, but wish the barrel was longer for reasons listed above. I ponder now and then about having the barrel replaced and chambered in the .25-35.
