It looks like there are several DS fans here. If you ever get the chance, pick up a Colt SF-VI or DSII. They are stainless steel versions of the DS.
My SF-VI has a lighter and smoother trigger than the 2 DSs I have, and there is no stacking typical of Colts.
They didn't make these guns very long, so they aren't all that common. If you really want to go all out, find yourself a Colt Magnum Carry, the .357 Mag version of the DSII. They only made them a couple of years too and prices have gotten ridiculous on them.
