Like the look,feel,and features of the 5906, but feel it might be a bit heavy for me, being a light-weight male with relatively small hands. Would like opinions of the 5906 vs the 6906 vs the 3913. Does the 3913 have a lot of recoil ? I plan to use the pistol for home/business defense, but might at some point conceal carry(legal here in VT). Thanks for any input.
