The New Model 3 Double Action was actually the first K frame stock design for butt-frame. A set of K frame round-butt stocks will fit this gun, except that the front lower corner on the 44 DA butt-frame has a sharper turn than the Models 1899, 1902, 1905 guns. Any after-market K frame target stocks should fit your revolver. Remember that all pre-WWII guns had their stocks hand-fitted to each gun, taking off both metal and the stock material until a perfect fit was accomplished. This means that every gun may have slightly different dimensions.
