J-frame rebound spring UPDATE

[71velle]

I would like to slightly reduce the trigger effort on my 642, it has already been fired a good bit as well as dry fired a bunch. I have read mixed reviews on the the spring kits and decided that I do not want to change the main spring. Wolff claims the factory spring is 18 lbs and the have replacement form 12-16 lbs. Since I am not looking for a light trigger I was thinking that a 15 or 16 lb replacement spring. Any experiences would be great, I would love to get it right on the first shot.

Like you, all my J and K frames have factory mainsprings, but I've installed Wilson Combat 13 lb rebound springs in all of them. I'm very, very happy with the result.

I too like the Wilson Combat 13 lb trigger return spring. That said I also use the Wilson mainspring. To offset the lighter main spring I install the Cylinder and Slide extended firing pin. I never have any FTF with this setup. My current 629 has a double action pull of about 8 lbs 10 oz while the single action is a crisp 3 lb 4 oz. I highly recommend getting the Lyman trigger pull scale. It is invaluable when u are doing trigger work. Heck I take it with me when I am checking out new guns.

Thanks guys!!
I can imagine a trigger gauge would help to fine tune. The problem I have is that I just start to shake pulling the trigger, so Im thinking a small change would make the difference. I was a little concerned that 13 lb would not have a crisp reset, but if you guys like them it would be worth a try. I just noticed that I can get a 12-16 lb kit for $9 so I shouldnt have to order twice.

Since I might have to do it a few times is it worth it to make or get the special tool?

With my neuropathy, shootin' my favorite snubby with any kind of accuracy got to be a bit difficult.
I switched my main spring with an 8 pound Wolff and my rebound spring with an 11 pound Wolff. To help insure proper function and reset, I smoothed the innards a bit with an extra fine Arkansas oil stone.
I've never had a light primer strike, in fact it dents the primers deeper than a factory stock m66.
It was worth it to me to get the special tool.

No to the tool. I have one but saw a Jerry Miculek video where he used a Bic pen to remove the rebound slide and put it back in place. It worked really well when I tried it.

I put Wolff reduced power main springs on two J-frames and they helped reduce trigger pull without compromising reliability. Changing the rebound spring only made no noticeable difference when I did it.

I use 11lb rebound and 8lb hammerspring on my 60LS, but this gun is for competition only and will only work with reloads with Federal primers

Every hand and revolver is a little different -- you'll have to experiment to find what works best for you and your firearm in combination.

I have tried both factory and Wolff standard power mainsprings with 13-16lb rebound springs in a 442. I found no substantial difference in trigger feel versus the factory set-up.

What made noticeable difference in action and groupings was a gentle, informed smoothing of all contact surfaces in the revolver.

Just installed a 15lb spring. It feels good, lighter but still has a good reset. Install was pretty easy didnt use any special tools. Hopefully I can get to the range tomorrow!

I use the Wolf 11lb rebound springs after polishing inside with a stone and paper. Never had a problem with a 8lb Wolf mainspring in a J frame, but usually install the 8.5lb.

71,

In my limited experience, Hapworth has it nailed. Trying different rates for each spring to get the pull and reset balanced to your shooting feel. The best I can explain is the pulling and resetting feeling like a circle, and not a linear back and forth. Once you nail down getting the hood open, no reason to not experiment a little.

Wow with an 11lb spring I bet it feels light!! The kit I bought has 12-16lb springs but I dont think I want it any lighter. Maybe I will take the tools to the range and try a few springs, since its not hard to change.

 

[71velle]

After some range time I removed the 15lb spring and moved down to the 12lb spring. The 15 was defiantly a nice improvement, but with the 12 I still have a solid reset and even better pull. Still not a light trigger by any means tho. If I had an 11 lb spring I would have tried it.
