this was a gun customized by bob munden for fast draw competition. the trigger pull is a little under 1.5 lbs, and its reinforced to handle fanning, the hammer is made for fanning and fast draw. its a dream to shoot. very smooth and light action, and very quick. with wax, and with cowboy action loads.
on a side note, i shoot cowboy action with my vaqueros, the colts just aren't built to take that kind of use. they are older 44 mag vaqueros, i run 44 special through them, except when i practice gunfighter, i use stout 44 mag loads to control my recoil.
i should post my other SAA, its just a plane jane 2nd gen artillery.
the buffalo bill center has another one with the same hammer, it was a race gun that ended up with his wife. takes a while to get used to the hammer but its actually a fairly comfortable design, even outside of fast draw.
