Stiff Double Action Trigger Pull

I have a Model 19-2 with a 4" barrel that has a consistent 4 lb. single action pull which is clean and crisp. However, the double action pull, which I prefer to use, is off the scale of my 8 lb. trigger pull gage. If we were talking about a model 1911 the problem would be simple to fix but this is a Smith & Wesson revolver. My experience with revolvers is limited and before I start taking things apart I want to make sure I won't do more harm than good. Have any of you tried to lighten the double action pull of a Model 19 and if so, how much trouble did you incounter?

The most common kitchen table gunsmith job to reduce trigger pull is to go with a reduced power hammer spring. Pretty simple job. Remove the grips to access the hammer spring. Loosen the tension screw in the grip frame and remove the spring. Replace it with a reduced power spring. Several brands on the market.

Sounds easy, right? The problem is light primer strikes. On some guns, you end up with failure to fire and it can also be more of a problem with some brands of ammo than others. Further, no way to predict until you get out and test the gun. If this is a self-defense gun, you're playing with fire. I am not a fan of reduced power springs in revolvers for that reason.

The right way to do it is open the action, polish and hone and so on, BUT a S&W is not a gun you open up to play amateur gunsmith, not unless you want to end up with a box full of parts. Take your Smith to a gunsmith who knows S&Ws and make sure he know Smiths.

Thanks NCG for the quick reply. I have a local gunsmith that has worked on my S&W revolvers in the past. I'll give him a call tomorrow.
I agree, if you don't have a lot of experience or training with any kind of weapon, leave it to the experts.
The life you save, may be your own.

Thanks TGR I watched the video clip you posted. Very interesting indeed. I still think I'll be calling my favorite gunsmith and get him to do his magic, better safe than sorry.

I have done a lot of action work on S&W revolvers and some on Colt DA revolvers. I NEVER lighten the mainspring that drives the hammer for the reasons NCG mentions. The rebound spring that TGR mentioned returns the trigger forward. In the past, S&W did a lot of hand fitting and smoothing which the early revolvers were designed to get. When this got expensive they cut back and increased the rebound spring pressure to overcome resulting drag. If the gun is worn in or the parts are polished or smooth this spring can be reduced a bit safely but you don't want to go too far or the trigger may stick back or return slowly, especially if dry or dirty. I like a brisk return for fast DA work.

I find that pull weight is not as important as some think. Smoothness is the key. It should be smooth without grittiness or catches and should not stack. A full weight pull will feel much lighter if it is smooth and consistent and with a proper grip you can fire it with great speed and accuracy. .I would be leery of a DA pull that was 8 pounds or less and prefer a bit more. If it is properly smooth it will work very well. A good DA pull is very conducive to the surprise break you want in precision slow fire and I used to be better with slow DA fire than my friends shooting SA with revolvers at 25 yards.

Interesting stuff here. I don't have any experience with a S&W DA so I enjoyed reading this thread.

Yeah it is. Mac makes a lot of sense.
It's easier to push a ton on ice, than a few hundred pounds on asphalt.

S&Ws are easier than Colts. Colt tend to have parts doing multiple functions so it's easy to work on one aspect and screw up another. I have had professional gunsmiths screw up badly on Colts. It is hard to find one who is good any more.

I used to lighten the rebound spring more after smoothing and polishing everything but I found a faster reset better so I go just a little lighter than stock if at all. They really do feel surprisingly light if they are smooth and even. I prefer a good DA trigger for moving targets.

" I love to hone action and replace the rebound spring ." is normal for me to do . My 638 S&W is a Talo I was not able to improve the DA on that gun without slowing the trigger reset , I put it back to stock .

Now that being said my K22 master with 8 3/8 barrel I use in paper punching only and long range metal pistol silhouette shooting I converted it to SA only and the trigger was set under 1 lbs and I reduced hammer travel by 25% and increased weight of the hammer spring to speed up lock time . This really help on 100 yd offhand shooting .

TGR,

I would bet that Talo was nicely tuned from the start. On the SA K22 I know the factory used to sell a SA only version but I would bet it was not set up as sweetly as yours. That must have been something. I had an 8 3/8" barrel once, bought it at Raleys supermarket in Sacramento, but it was a bit long for me. The 6" without underlug that I have now is about perfect for me. I looked for this for a long time.
