This is for a home-defense weapon. I am not looking to go hunting or target shooting

Check the mfgs data for muzzle rating. It should be cylinder and no constriction designations like skeet, modified or full. You want no sizing change from cylinder for HD.
Research the pattern of both guns at <20 feet. (A typical indoors HD shot distance.)
My guess is, in that short distance, the pattern has little time to form (with a 1.5" barrel length delta) and would be a wash. If you find data, please post it so this barrel issue, with regards to HD can be put to bed. If no statistically significance pattern delta, I would go with capacity.
