Try carrying the 29 in your pocket for a day and then tell me which one is superior.
Oh c'mon. You know what I meant. The Mod 29/629 is obviously a big heavy mutha. I owned both, and I know which was good for what.
And I had a lot of unmushroomed hollow points come out of the snubby SP101. Not enough muzzle velocity. Test it yourself, using Hydra Shocks.
