I had a 3" SP101 that the previous owner had bobbed the hammer spur on. I liked it less than the 2" DAO one I had owned previously.
I traded it straight across for another 2" DAO gun, whose owner was fond of the CT lasergrips he'd had on it. The lasergrips complimented the 3", while the facory rubber grip w/ Altamont inserts compliment the 2" gun, in my eyes/experience. YMMV.
