Default Light trigger pull - can I...

Older Mod. 14 .38 SPL.

Trigger pull is light, about the lightest I would consider safe. I assume a trigger job was done. Sideplate screws show marks.

Am I right that the light trigger pull is accomplished by modifying the original sear surface?

And that this can not be reversed except by installing a new hammer?

And that the mainspring adjustment screw has no effect on the trigger pull weight?

Thanks.

And that this can not be reversed except by installing a new hammer? If sear is damaged, might be possible to fix, might need new parts. Need expert revolver smith to check.

And that the mainspring adjustment screw has no effect on the trigger pull weight? The mainspring adjustment screw has a large effect on the trigger pull.
Thanks.
Sounds like you need someone who knows what they are doing to check your revolver.

I have not been able to get the hammer to push off.

I don't suspect any damage to the sear, I'm just noting the light trigger pull.

Should I simply replace the springs as routine maintenance?

Are these springs best bought direct from S&W?

Is the mainspring tension screw's normal position to be screwed all the way in?

Thanks.

Taco: The Model 14 is referred to as "The Target Masterpiece." It came from the factory with a lighter than normal single-action pull intended for target shooting. I have a target model 19 and it's single action pull is extremely light.

Now all of that is not to say your trigger was not further lightened, but just that it was lighter than normal to start with.

It may well be that the trigger weight is within specs and safe, but feels odd because that model may have been set differently from others. It is possible to get an amazing trigger on a K frame without being unsafe. You might just need to have it assessed by someone real familiar with the nuances of that trigger.

Good advice. I'll tighten the mainspring screw and try again. If it still seems light, I may need to look under the hood...

Thanks.

The screw shoud be all the way tight; it is NOT meant to be an adjustment.
Rather than guessing, if you measure the single action pull at 2 1/2# or more, it is good to go. If you don't have a gauge, a small exercise weight and a coathanger can get pretty close.

Most my old K frames have a single action pull very close to 2 3/4#, bone stock, no mods, no light springs, just shot them as they came.

Just my opinion...

If the gun is strictly for range/target use, unless you are getting failures to fire, I wouldn't mess with it.

Target is what I plan to use it for... but curiously it arrived showing a good deal of holster and carry wear.

I'll see if I can find a 2.5 lb. weight and test it out...
