Anyone have a Wolff spring kit make the trigger WORSE?

[915]

Gun in question above, Model 13-3 3” in nickel.

Bought it in 2012 on a whim for $389, probably the best foresight I’ve ever had, not knowing a single thing about it when I bought it. Been an outstanding gun with a wonderful trigger, save for intermittent failures to fire with CCI primers, particularly the Speer Gold Dots I prefer to carry.

First thing I did was check the tension screw, tight as could be. I wondered if maybe the springs had gotten damaged or worn out, so I got the Wolff spring kit for it. Put the new hammer spring and the lightest included trigger return (12#).

Failures to fire went away, but I swear it ruined my trigger! It feels a pound or two heavier and even slightly rougher. Reliability is more important, but what the heck? It’s still a phenomenal trigger, but I didn’t expect that result.

The trigger return spring out of mine looked to be the same as Wolff’s heaviest (14#), but the hammer spring in the Wolff kit was thicker (harder to put under tension) than the one that came out of mine. Anyone else had this happen?

Wolff makes two types of mainsprings. The Type 1 is full power and Type 2 is rated as reduced power. Which one did you install in your gun?

You replaced an apparently weak mainspring with a fresh spring, that may help explain why the trigger pull is now a bit stiffer. As your fail to fire issues went away with the change I believe you were on the right track.

Also, new rebound springs do look to be longer than one that has been in the gun for awhile. They can be fun to install. Once installed, over time it will take a set and will be a bit shorter the next time you remove it.

Sorry, should have specified that! It was the reduced power. I was hoping that it would keep the pull the same while improving reliability.

Might smooth out a bit with some more rounds through it, which is all the excuse I need to shoot it some more!

Yes! On a Polish P64 several years ago!

There is no law that says you have to use the return spring from the Wolff kit. If it were my gun, I’d take it apart one more time and do two things. First, I would reinstall the original return spring (you hadn’t experienced any failures to reset had you?). Second, while it was already out I would polish the curved hooks at the top of the mainspring where they engage the stirrup of the hammer, not removing any metal unless there were burrs that got by Wolff’s QC. A tiny drop of good gun oil or even light gun grease there (and perhaps on the inner, sliding surface of the return spring block) and it would all go back together and out to the range. A couple of rounds should show you whether the problem was solved, and a couple of hundred rounds will make everything settle in about as well as it will get.

PS I didn’t mention it, but while I had it apart I would automatically look for any burrs turned up inside by my previous work... that roughness had to come from somewhere!

Thanks, I’ll try that! While I had everything apart, I thoroughly cleaned and degreased everything, and put a little synthetic gun oil on the articulating surfaces, but didn’t put any in the trigger return spring channel...could be part of the reason why it feels a bit “catchy” on return.

Will definitely look at the mainspring V also, I did lube that, but it feels slightly less fluid than it did before when pulling in double action.

Oddly enough, the SA trigger pull improved vastly, and it was already excellent to begin with. That’s probably more related to the cleaning than the spring work.

Thanks Froggie, you were spot on! I put the original return spring back in, there were some small burrs in the V that I filed down, and made sure to lube the spring channel this time. Back to the K-frame smoothness we’re all used to!

the softer return springs give problems with trigger reset. They are usually sold as a set to ensure trigger return.
If it was really stiff then its possible something wasnt put back right

Main springs!

Look at your original main spring! It will probably be arched! A NEW main spring is flat! The main spring will arch over time(10K, 20K, 30K rounds)! The more it is arched the lighter the DA pull becomes! You replaced the old spring with a new flat spring! When you lighten the trigger pull you will end up with "hitches & catches" you never had before! This requires polishing the moving parts of the firing mechanism. The DA pull is a product of the trigger return spring and the main spring. The SA pull is a product of the main spring and the SA sear angle. A worn SA sear will cause push off of the hammer!
