I own both the 2 1/4" and the 3" versions of the SP101. Both guns are extremely accurate and to be honest I can't tell a discernible difference in the accuracy. I can tell you the 3" version has less muzzle flip when shooting full magnum loads. The 2 1/4" version tends to roll in my hand with magnum loads. I changed the grip on the 2 1/4" and that helped to reduce rolling. Both guns IMO are too heavy for pocket carry, but work very well IWB and OWB. I carry my 2 1/4" in a Simply Rugged Silver Dollar Pancake and a my 3" in a Bianchi 7 Shadow. Both guns are easy to conceal. I do however recommend wearing a good belt. Whichever version you choose you will be very happy. I don't think you could go wrong with either.
