More discussion here:
Page 2 of the thread features opinions (that make sense to me) regarding 147 from a short barrel.
But I'd try some 124gr. and 147gr., to compare recoil, reliability in your gun, and muzzle flash. Maybe even try your final selection with milk jugs, so you can see how it expands when shot out of your gun. Never know when you'll be threatened by water-filled plastic jugs anyway.
