My suggestion would be to try and duplicate a George Mathews custom carry revolver from the late 40's to the early 70's. You can see pictures of these in the 1970 guns and ammo annual as well as on Mike Priwars' pictures in his album pages here on the Forum. Some of the modifications performed were, thinning the trigger guard, shortening the barrel to 3 or 3 1/2 inch, modifying the hammer, smoothing the trigger, building and fitting a custom rib with an adjustable integral rear sight{one assembly} and otherwise making the revolver very easy to use for "professional" daily carry. Contact forum member SG-688 for additional pictures and advice. All my best,and good luck on your project, Joe.
