I'm curious about the double action trigger weight of a Wolf reduced mainspring in a revolver. And how that compares with the stock S&W mainspring. It seems odd that Wolf provides the weights for the various rebound springs but not for the mainspring. Is that because the double action trigger weight would vary so much from revolver to revolver depending on the amount of smoothing of its innards?

I know that I could just buy a trigger weight gauge, but I haven't been curious enough to spend the money. If there is no stock answer and I do have to buy the gauge, which one does everyone here use?

I can't answer that one. As far as I know, they just label them (KLN frame ribbed type) as standard or reduced power.
I picked up an older mechanical trigger pull weight gauge on Ebay for just a few dollars.
 
Whenever I do a trigger job on one of my S&W's I always use a Wolf reduced power mainspring. I used to replace the rebound spring with a Wolf spring that was lower than the S&W stock rebound spring. I no longer do this, even on a revolver that I have smoothed the working parts well I still prefer the S&W standard weight springs ability to positively reset the trigger after every shot. That's just a preference I've developed in the 35 yrs. since taking S&W's Armorer's Course while a student in the Gunsmithing program at Trinidad State College. I have tuned many S&W's that way over the years and had few complaints. The reduced power spring does need to be replaced more frequently than a regular power, you'll kow when it's time as you start to get light primer hits that fail to produce ignition. I buy my reduced power springs from Brownell's in the three pack so I always have a spare at hand. In a pinch you can re-arch a weakened spring but replacement is the better option.
 
From the Wolff site:
HAMMER SPRINGS (Mainsprings)
Reduced Power...: 8 Lb.
Factory Standard.: 8.5 Lb.
Extra Power.........: 9 Lb.
Note: Models 317, 650, 651 have a 12 Lb. factory spring
 
Oops, I should have limited my question to K, L, and N frames!

Thanks, Mr. Wiley. You have pointed out an essential ambiguity in my question.

I wanted to know the weight of their mainsprings for K, L and N frames, but I stupidly assumed that bit of essential information, as I had already gotten the J frame information from Wolf's website.
 
No, you're right. In my haste to be helpfull I posted when I should have thought longer.
 
You might be interested to know that the standard Power Wolf main spring still gives you a lighter trigger pull than the standard S&W main spring. I use the Wolf standard power in my revolvers with good results, since I do not try and get a five pound trigger pull on a revolver [slight exaggeration]. A lot of folks think they will shoot twice as good with half the trigger pull, not usually so!
 
I just replaced the main spring and trigger reset spring on my 20+ year old model 60-2 snub nose. I used the 8lb mainspring and 14lb trigger reset spring. The trigger reset is very nice and quick but trigger pull seems too light. I only use DA and after 20 years of use I'm not sure if I like the lighter pull. Wolfe reduced power spring kit for J models was used.
