Stepson has a model 14 that I noticed suffers from "Push Off" at about 10 to 12 pounds per bathroom scale. Is this a DYI or qualified gunsmith repair?
Thanks

Terry,
The manual calls for "nominal" pressure to check for push off, which to me has always been around 8-10 pounds. This was confirmed by the instructors at the S&W armorers school. Any hammer trigger interface will push off if subjected to undue pressure.
Extremely light trigger pulls can also be a telltale sign of tampering and push off issues. If you have a trigger pull gauge, check to see if the trigger pull is around 3 pounds. Anything below 2.5 pounds is an indication of possible modification, tampering, or excessive wear and tear from use.
(Excessive hammer or trigger sideplay can also contribute to push off)
There is a bench procedure to repair push off that works very well, as long as the bevel on the trigger and the cocking notch on the hammer are in-tact, undamaged, and unmodified. A specific sized India stone and technique are required.
Unless you are familiar with S&W's "benchtop" method of sharpening the trigger bevel, I would ask a trusted local gunsmith, if you are fortunate to have one in your area, if he would check the SA and provide an opinion concerning the integrity of the SA interface.
You might also check to see if the rebound spring currently in the gun is a factory spring with 17 coils. A lighter aftermarket spring, or a spring that has been cut can contribute to push off.
Replacing the lighter rebound spring with a full length factory spring will sometimes solve the problem, without any further intervention or modification.

Thank you A951 for the quick concise reply.
After I discovered it I compared it with other S&W revolvers I have. I could not reproduce the push off with any of the other revolvers I have.
The trigger pull in both single and double action are smooth, crisp, and pleasant. I will look around and see if I can find an old school gunsmith locally. Most of the ones around here are AR put and take mechanics.

First things being first, have you checked then mainspring tension screw at the bottom front of the grip-frame?
