Hello all-I have a question that's been bugging me for a while and no one has been able to give me a conclusive answer. I have the opportunity to get my hands on a Beretta Laramie (SA Schofield copy). However, I really don't like SA, but love the styling of the gun itself. I found out that the Harrington and Richards 949 was a DA gun styled after a SAA gun, but I'm not a fan of the .22. Is it possible to convert a single action revolver like the Schofield to a double action revolver?
