I'm going to guess with a grinder. All you have to do is take the squared corners off the bottom of the gripframe. My Security Six is going to the gunsmith for similar treatment soon.One question? How did you get that round grip on your shorty Security Six?
That sounds like a square-to-round conversion grip.My Security Six has a round-butt rubber grip even though it has a square butt frame.
Yep, I used a grinder. I took a pair of round Ruger grips and put them on the square butt. Then I used a black marker to outline the new shape. Then I turned on the grinder and simply rounded them. Didn't bother refinishing them, though it wouldn't be difficult -- merely unnecessary.How did you get that round grip on your shorty Security Six?
I think I know where the confusion is comming from.It resembled every other DA on the market. I don't know why you would think it was like a single action or why that would be the reason for the redesign. As far as ease of manufacturing, that is what Bill Ruger told R.L. Wilson for the book "Bill Ruger and His Guns".
What about this is different from any S&W DA?
That's arguable. No such distinction is made between Blackhawks and Vaqueros, even when converted to five-shot .45Colt, .475 and .500 Linebaugh.
