Since Erich asked, here is my 3" DS with Spegel Boot Grips:

Craig just started doing Boots for D-frames recently. This gun is actually now back to its Badgers, since I need to do just a tiny bit of fitting on the Spegels and have not had time. Craig warned me that fitting is more likely to be necessary on Colts than on Smiths, since the frame cutouts at the top of the grip window are cut individually, rather than being drilled straight through, as on Smiths. FWIW, the Badgers are a little more concealable than the Spegels, but the speedloader cutout on the Badgers needs more relief. Both feel equally good in my hand.
