Just bought a new 432-3 (.32H&R Mag). Love it, but the trigger pull seems easier than my 442 (.38 Sp.). I actually prefer the stiffer pull of the 442. Anyone know if the springs are different, and which weight or type each gun has? Thinking about having a gunsmith put a stronger spring in the new 432 to make it like the 442, but not sure what to buy.

The factory spec trigger pull on your 432 revolver is 10 pounds, according to the S&W website.
Wolff Gunsprings makes an assortment of rebound and hammer springs for the J-frame, including 8, 8.5 and 9 pound hammer springs and different rates of rebound springs. They list the factory hammer spring rate as 8.5 pounds.
You could likely increase your trigger pull by adding a heavier 9 pound hammer spring.
Be ready for the incoming barrage of posts concerning why you would want to make the pull "heavier".

Yeah, most people want a lighter trigger pull, not heavier. Before changing springs, shoot it. If it fails to ignite primers, then it likely does need a heavier main spring or at least a longer firing pin. Also, if it fails to ignite primers, being a brand new revolver, it should go back to S&W. Let them change the spring and/or firing pin as a warranty issue. Part of the purchase price includes the cost of that warranty.
Thanks Carter, I like the stiffer pull as it seems to me a little more of a safety feature...might make an negligent or accidental discharge slightly less likely. At least that's what I was thinking.The factory spec trigger pull on your 432 revolver is 10 pounds, according to the S&W website.

Yes sir, that's a good point. Another positive outcome is that a slightly higher hammer spring rate also makes these small revolvers more reliable under harsh conditions.....like daily carry, for instance.

The factory hammer spring on a j frame is 8.5 lb, according to Wolff, which they sell. They also sell an 8 lb reduced power spring, and a 9 lb extra power spring.
The other component that affects pull weight is the trigger rebound spring. Factory spring is 18 lb. Wolff sells reduced power springs from 12 lb to 16 lb.

I pulled my new 632 apart after its first range debut. It fired all 50 rounds but the firing pin indent was weak. It was Factory ammo from Lost River, so not sure what primer was used. Silver colored so may have been soft Federals.
S&W Marketing describes the UCR revolvers as having an "Enhanced Trigger" translates to me as reduced power springs used.
My 632 will be used for carry, so it has to be 100%. An investigatory look inside was warranted by the shallow primer hits. I was either going to change the mainspring or firing pin, depending on inspection. Not going back to the Mother Ship....I'll fix it myself.
I can tell you that the rebound spring is green in color. I believe one of the after market vendors has green rebound springs but can't tell you what one. Mainspring is colored also. I would bet that both are reduced power.
Ended up my firing pin was short @ .490" and profiled to a point. You can install the heaviest mainspring available, and it won't help if the pin doesn't have the length. Info I have recommends minimum of .495" with .505" being optimum. I installed a Power Custom Extended Pin. It measured .505". Kept the S&W OEM springs that came with the gun.
If your gun is igniting all brands of primers reliably the mainspring change should accomplish your desired goal. IDK if I'd go the 8.5 (stock weight) or 9 pound.
