I had a buddy ask me if you convert a single action revolver to a SA/DA revolver.  He didn't ask about a specific model or anything.  So lets say a N frame S&W.  Can it be done?

I cannot see it being done for less than the cost of buying a new gun. The frame on a single action (like a Blackhawk) is very different than a GP 100 frame. I cannot see how you would fit and align the double action components in a single action.

BTW an N frame S&W is already SA/DA.

No.  Not even remotely feasible.

That's what I thought but didn't know for sure.

On the other hand, S&W used to offer replacement hammers to convert K-frames from DA/SA to SA-only.  This was primarily for bullseye competitors who thumb-cocked for each shot.  Pulling the trigger with the SAO hammer uncocked would merely advance the cylinder.

All N frame S&Ws are double action anyway. Not sure about your question. Are you talking about an N frame that was converted to SA and converting it back?

He wants to convert a DA pistol to SA for awhille they go back to DA if needed.

Does he want it to be SA only?  I'm not sure why he doesn't just cock the hammer manually for each shot if he has a DA revolver.  Are we using the same definitions of the terms SA and DA?

SA = The trigger does one action, fires the gun.

DA = The trigger does two actions, cocks the gun then fires it.

And the answer no matter what he wants for the action of the gun is it's cheaper the buy a gun with the action he wants rather than have someone design, machine, assemble, and troubleshoot a custom action into a revolver not designed for that action desired.

The purpose of the trigger in the two different systems is pretty wildly different.  The mechanics of adding a bunch of function to the trigger in a SA seems somewhere between very difficult and impossible.

It's something to do with the handgun laws in Iceland.  You can only have SA revolvers but he likes the look of DA revolvers and wants the DA pulled from a gun and SA installed to be compliant.

Smith made some single action only 38 target guns, Model 14 as I recall, but they are long out of production and were never common to begin with.  I imagine a standard DA K frame could be converted, if Smith still had the parts.

I might be slow, but that's the exact opposite of what your original post says. If my brain is working correctly.  


I think without knowing what model he has, and what it is EXACTLY he wants to do with it, we might be peeing in the wind here.


From your other post it seems he doesn't even have one. OK.  So he want's a DA revolver to only shoot single action.  Is that what you are asking specifically?

You can't shoot model 14's in DA?????  I didn't know that.  Wow.

(Assuming you aren't being sarcastic...)  No, that is not correct.  Most M14s are DA.  IIRC they just made some for the bullseye shooters that were only SA and optimized for SA since that's how they shot them in competition.



Making a S&W single action only is as simple as removing the part labeled "DA Fly" in the photo above.  If the regulators will accept the simple removal of a part as compliance will have to be determined.

Correct, the SA-only hammers S&W installed in these specialty M14 and offered as aftermarket parts for other K-frames were not machined to accept the DA fly.  The pin hole wasn't even drilled.
