Spring kit question/ other issue

[DLWinner]

Hi!
I recently picked up a used like new 442. I have shot it approximately 250 rounds and decided that I would like to install a WC Spring kit. I have installed lots of these in the past with no issues. I was wondering…. Is it possible to only change the hammer spring? Is it really necessary to change the rebound spring also?

ALSO…
On this 442, I noticed that when the cylinder is spinning(while closed and unloaded) you can hear multiple clicks when rotating the cylinder before it stops. I checked other revolvers and none of them seem to do that. Anything I should look at when I have it apart?

Thanks!

I used a Apec Tactical J frame kit on a 360J that had a 13lb + DA trigger pull . There kit also comes with a firing pin replacement and has been a great upgrade and reliable when testing with Wolf small rifle primers , fed , winny and cci pistol primers too
Know idea about cylinder rotation !

I noticed there is a click right before the cylinder stop locks into the hole.

Of course you can change individual springs. Keep in mind that spring changes may induce malfunctions, and can have and negative affect on reliability. In other words, the firearm may not work as designed after your alterations.

Keep that in mind, especially if the gun you're modifying is used for personal protection.

The clicks you are hearing from the action are probably normal, and are the result of interaction between the individual parts inside the action. These sounds or "clicks" from the internals may differ slightly from one revolver to another. This is due to clearances and slight differences in the fitting of individual parts, and how clean or filthy the revolver is. The cylinder stop, DA sear, the single action cocking notch, and the stop notches in the cylinder all contribute. (some clicks or sounds, or the absence of them, can indicate problems)

BTW, these sounds or clicks, and the timing of them, actually help indicate the "integrity" and proper interaction of the internals. Consequently, if you become familiar with them, and listen carefully, they can assist when attempting to diagnose problems with the action.

Music to my old ears.

Remember also that some J frame trigger pulls are simply awful with current revolvers so you change parts and test it . A few hundred rounds fired tends to prove it ether works reliably or not . Thats also I try small rifle primers in test loads .

Changing springs in a revolver-especially a J frame-is a dance between trigger feel and reliability (the gun has to go bang and the trigger has to return promptly ALL the time). Also, remember that springs do let down in tension somewhat after some use. More than what you've currently fired. An initially reliable combination might not be somewhere down the road.

Given the low mass of the J frame hammer, the advice used to be to leave the hammer spring alone. YMMV.

Leave it stock

The heavy double action trigger in a J-frame is your "safety" should you ever have to draw it in a self-defense situation and the adrenaline is pumping.

You'll likely forget the "keep your finger outside of the trigger guard" rule and start pressing on it before you mean to.

You don't want a lighter trigger on a revolver you carry for self-defense.

I have 2 642 revolvers. One is about 20 years old, it has a Hillary hole, the other maybe 5 years old, w/o the hole. the later gun had a super strong mainspring. I replaced it with a standard power Wolff mainspring, now it's about the same as gun #1. Bot now have a good trigger pull. I didn't change the rebound spring. S&W Q/C is rather bad these days.
