You could always pull the hammer and grind off the single action sear. It wouldn't be reversable, you'd have to buy a new hammer to restore SA function. I've tried rapidly dry-firing mine in DA mode, and can't imagine it being an improvement over having an SA trigger after the first shot.
Yep I will have to get it back to C&S for their input. They did some work on the gun earlier to get it to shoot right. Great guys if you can wait. Thanks guys great Forum. I take a lot of .....for carrying my PPK/S but I like it and as a last ditch backup loaded with Gold Dots it serves the purpose.
