I'm working on an early pinned & recessed 8-3/8" 629 I bought a while back. The gun is mint with few rounds but did have push off and too light an SA pull, Anyhow, the price was right.....so I bought it. I easily fixed the push off issue using a S&W armorer approved method but SA is still too light for my tastes....about 2 lbs.

Springs had been messed with so I replaced the rebound and main with stock spec springs.

The hammer notch looks fine (no chips or damage) under magnification as well.

What else can be done to increase SA pull?

If you touched up the trigger nose by just lightly dragging a stone across it at the correct angle, it should be okay. Try wiping off all lubrication on the hammer full cock sear notch and the trigger nose.

I've found that the rate of the rebound spring has the most effect on 'felt' trigger pull. Even on single action. This is just my personal observation and I do not know if anyone makes a heavier than stock rebound spring.

I think I heard that the S&W factor shooter, Jerry M. uses very heavy rebound springs, so he can shoot so fast. The trigger returns as fast as he can move his finger.

Abflyboy is correct. When a friend and I were playing around with ISU Centerfire Matches years ago, we "Discovered" that a difference of one pound in the rating of the rebound spring would result in a one-quarter-pound difference in the SA pull weight. This was IMPORTANT in the ISU Centerfire Matches, as the SA had to be at least Three Pounds--but there was no advantage to being over by a LOT.

I have SINCE "Discovered" that this same ratio--one pound diff. in the rebound spring rating equals one-quarter-pound difference in the pull weight--also SEEMS to apply to the DA trigger pull, at least with K-Frame and L-Frame guns.

Also, the "Stock" Rebound Spring is "Rated" as being eighteen (18) pounds. Hope this helps. Paulie686.
