Model 63-5 Wolff spring kit issue - need advice

[OldNerd]

Hi, I recently acquired a 63-5 revolver. Bought the Wolff kit to lighten the trigger (I have small hands & mild arthritis).

Put the 8# trigger spring in, works great, trigger improved!

Tried to put the 14# return spring, did not fit, read forums, others said to cut off a few coils. I cut off 2 coils, got it in the gun, but now the trigger is grumpy. Sluggish and sometimes gets stuck. Tried the 13# with 3 coils cut, got stuck every other pull.

Any insights as to what went wrong or what to do? Should I order a new 13# or 14# spring and put it in without cutting any coils?

I emailed Wolff tech support, but since it's Thanksgiving I'm sure I won't hear anything until next week. I can wait, but it nags at me it when I can't solve a problem.

Thanks in advance for any help.

One other weird thing I noticed when I got the gun, the cylinder release button is kind of tight, and the cylinder is a little sticky to swing out. They work but i have to wrestle with 'em a little.

Possibly the inside of the rebound slide is inhabited by burr's, which is common. Sometimes problem can be cured by inserting a drill bit backwards in your electric drill chuck, then running the smooth shank now protruding inside the slide. If the slide interior is really rough you may need to run drill bit BY HAND that is a fairly tight fit. follow that up with the smooth shank burnish.

You may get by with the original rebound spring after the polishing. The 14# should fit after the interior of rebound slide is properly sized and burnished. Likely you will need a full length 13# to get the optimal trigger action for you, abet with a tad less return "snap" than with a more powerful one.

Several thoughts… the Wolff springs are not designed to be cut. It will fit. There is a tool out there made to install the spring in the rebound slide but I just use a small Phillips screwdriver. The cylinder release “tight” needs to be described a little better. Is it just hard to depress and open they cylinder? See if the extractor rod is tight - it is left hand threaded. As far as the cylinder being sticky to open, check and see if the 2 round head screws have not been swapped. Lastly, since the model 63 is a rimfire, you may experience light firing pin hits and misfires since rimfire ammo usually needs more force than a centerfire to set off the priming charge.

Springs whether factory or aftermarket (Wolff) are designed to function properly without being cut, cutting causes the problems that you're experiencing. Check the hole in the rebound slide for burrs and lube it and the spring when re-assembling just a drop of oil is sufficient a light coat on the exterior of the rebound slide. The two round headed screws are not interchangeable, swap them and see if the cylinder is easier to open. Also check the extractor rod for tightness, if it has unscrewed this may be the culprit. A drop of oil on both barrels of the crane helps too. Hope these suggestions are helpful in solving the problems that you're experiencing.

You can remove and replace the rebound slide without the specialty tool; however, that thing is great.

I use a Cratex rod with diameter slightly smaller than inside of spring channel in rebound slide to smooth it out. I also lightly stone - just to polish - the sides and bottom especially of the rebound slide. Do not touch any surface on the top of the rebound slide.

The whole point of Wolff’s spring kits is to avoid cutting coils. Just try different spring weights until you get your desired trigger pull WITH RELIABLE FUNCTION.

Hello gents, thanks for these answers, all very helpful.

The cylinder release is hard to maneuver and sometimes requires retrying to disengage (release, push again). I'll try swapping out the two screws as suggested. I will also check the extractor rod.

I'll order another spring kit from Wolff. I will play with a couple different weights to make sure get consistent reliable rimfire strikes. I'll look for burrs in the rebound slide as well.

I'll let y'all know how it goes.

Happy Thanksgiving!
