Pistoleer: I recall seeing those years ago, but more recently I have seen the attachments that you can install to give you the same effect as that you would have with the Model 38, the Bodyguard. I know they (someone) used to make that attachment for the Colt snubnose revolvers and have seen those for the S&Ws but regrettably, I can't point you in any direction except to suggest you contact Gun parts corp/Numrich Arms or some of the other major parts places like Global or Samco. HTH. Mikey.
