S&W 10-6 double action only mod?
I just picked up a Smith and Wesson 10-6. Gun store owner said that it had a police department modification to fire double action only... and indeed that's the case. Cocking the hammer rotates the cylinder, but the hammer doesn't stay cocked. It works fine on double action.
Questions- was this a known modification, and how was it accomplished? Or is something busted?
Price was right, so I didn't argue, but now I want to know what was done so I can restore it to double or single action working.

Believe it was done by deleting single action notch on hammer. Years ago when I lived in calli the LAPD had a couple of bad shootings, they blamed on revolvers that were fired when the S & W's were cocked. Making them DAO was their solution to the problem. 0 -
Getting back to Single Action will take a new hammer.
Which should be fitted for proper timing, although you might get lucky and one drop in.
But that will pretty much wipe out that "right price."
You could just practice your DA shooting, it can be a valuable skill.0 -
It actually wasn't the guns fault, it was the operators fault for cocking the hammer and then holding a perp at gun point with it in that condition. We all know how little pressure it takes to set off a Smith when its cocked.
LAPD did the neutering work not only on duty guns but also "off duty" revolvers. These guns still turn up in stores and at auctions frequently. As mentioned it's a fairly easy fix. Just get another "K" frame hammer and have someone who knows what they are doing fit it for you.0 -
Ya, model 36's and 49's were also DAO when bought through the LAPD Revolver and Athletic Club store at the Academy. 0 -
There are tons of these DA-only revolvers on the surplus market. They're good bargains for defense guns. I wouldn't like one for hunting or target shooting, but they're ideal for home defense.
The NYPD, as one example, now mandates that *ALL* its duty and off-duty guns either be DA-only, or have a "DA-only" like trigger modification (eg the so-called "NY trigger" for the Glock).0 -
There is, or was, a competition course for law enforcement officers that was fired double action back to 50 yards. I don't know if the rules prohibited single action firing or if the competitors just preferred the consistent trigger pull for all shots. With practice and a smooth double action pull, very accurate double action firing is possible. 0 -
jonk,
In addition to the police department conversions there was also a style of competition named PPC for Police Pistol Combat or Practical Pistol Competition. The revolvers we converted for these competitions were all double action with the hammer bobbed. But as with all firearms competitions in the U.S., the hardware race overtook the original intent of the competition format and pistols evolved into highly specialized, high performance revolvers as opposed to the original simple designs. Intricate custom ribs sat on top of large diameter custom barrels with cylinders tricked out along with superbly light/smooth trigger jobs which would fail any sort of duty carry status.
Here is a short video of a 3-phase competition without all the stages of a certified course of fire:

I shot those PPC matches at the Police Olympic Games for about 20 years and used a 6" Smith model 14 with a non-bobbed hammer as did most of my friends. I shot single action at the 50 yd line and double at the closer distances.
Since action pistol was adopted in the games I shoot it almost exclusively. I now have a dedicated PPC revolver that is DAO and is as smooth as they come for when I decide to do PPC again.

Lefty is correct about the course of fire for the PPC matches. The 50 stage could be fired single or double action. All other stages needed to be done double action only. About 40 years ago I started in PPC with the San Bernardino, CA P.D. team. Most shooters used S&W's mostly K-frames. A couples of custom houses made quite a living building these revolvers - Davis and 300 were two of the best. The LAPD neutering program was just as described - no single action notch on the hammer. A simple swap out will cure that. 0 -

ny triggers for glocks are a weight thing, not an "action" thing. glocks only have one type of action. the ny triggers made it heavier than factory.
