Yammy, the best place to get the rubber grips is eBay. There are two "models" of Pachmayr that will fit. The
Pachmayr Compac, which is a one-piece that opens at the front strap and has either a Pachmayr or Colt medalion, and their other "compac"-sized grip which is in two pieces (no medalion). Both types need a screw which should be supplied by the seller. Both feel the same in my hands.
These little guns will still feel more snappy than a larger revolver. But the Colt DS is an easier shooting gun than any other 2" snubnose, other than the K-frame S&W 2" barrels (a larger gun).
Here is a photo of my two Det-Specs, with both types of grips.
Here is a link to an eBay search for "Colt" under "pistol -> grips". There were 397 items when I posted this. Most of them are for semiautos, but there are grips for the DS, which is the "D" frame. If your gun is from the mid-60s or newer, you will have the short square butt frame, which is the typical configuration, and you will have an easy time finding grips. If your gun is the older type: long frame or round frame, you must search harder. (mine are '66 and '74, both short square butt).

There are retail sources, but they all charge more for shipping, and you never know when they have any in stock. I bought mine through eBay with no problens whatsoever.
Enjoy your lil' Colt DS. You will find many here and elsewhere who have one.
