Anyone got an estimate for the trigger pull weight on a J-frame with internal hammer?
Are these double action only?

Internal hammer guns are DAO.
My 940 ran about 12 lbs, very smooth. I believe that it had been worked on by the gun shop owner who owned it before me, but that it had its factory springs.

Yup, they are double action only (there's no external hammer to cock).
Out of the box, the trigger pull on my 642 was about 13 lbs. After running 1000 rounds through it and dry firing countless times, it was still about 12 pounds but felt much smoother. I replaced the hammer and rebound springs with some lighter ones from Wolff and the trigger pull is now about 9 lbs.
Now the standard disclaimer: If you replace the springs in a gun, fire literally hundreds of rounds of different ammo through it to ensure that it will fire every time - before you trust your life to it. With that said, I had no problems with mine, even when firing ammo reputed to have "hard" primers (CCI, S&B, etc).
Temperature can also have an affect on the mechanicals; so to be sure, I've left the gun in my trunk overnight with the temp in the teens or single digits, then tested it out at the range cold. Mine still worked every time. Your results may vary.

What he said, be very careful when messing with the hammer spring on a J-Frame. My 442 has been misfiring after the last owner changed to a lighter hammer spring. Major gains in smoothness will come from polishing/deburring of internals rather than lighter springs. I'm having my springs put back to stock, but the benefits of the action job will still be there.
Above all I want dependability in my carry weapon.
