I'd gotten some various recoil springs from them over time, but once, I was reminded, I'd decided to polish up the action on an old S&W revolver and remembered a set of spring they make. In this case, mainsprings that drive the hammer, and the springs that return the trigger mechanism to rest position.
Allow me to cover those functions for those who haven't had to mess with them:
The hammer spring is exactly that. When you pull the trigger back, or pull the hammer back to cock it, that spring is flexed to drive the hammer down when the trigger is pulled.
The trigger return spring is a coil spring that fits inside a passage in the trigger mechanism. It keeps the trigger in place until you pull it or cock the hammer; when you release the trigger that spring drives it back into rest position.
If you get too light a spring(or grind the original down too much, and no, I can state I've never done this) a hammer spring, it will not reliably drive the hammer hard/fast enough to fire the primer; if it's too heavy it makes it harder to fire. If the trigger return spring is too light, it will not reliably move things as it should, which means, at best, the trigger will not reliably do its job; if it's heavier than needed, it makes the trigger pull heavier than needs to be. Both of these are often made heavier than need to be, because a pistol needed for self-defense HAS TO WORK EVERY TIME.
Which brings us to the monkey holding it.
Say you have a pistol that's for target, or small game. You want it to have a smooth, light action, and if you do mess up and make it a bit too light, it's not a disaster(unless it makes you blow a 'win the match' shot). So you have all kinds of 'grind and polish this, shorten that, and polish all these places) ideas, some of which can work, though the polishing can be done to excess and leave things a bit loose.
Wolff came up with a mainspring design, and a set of different trigger return spring weights. Idea is you can try their standard weight mainspring and one of their lighter return springs, and make sure if it works reliably* before you go off on your way, and I'd heard various good things about their parts. So, instead of starting with a touch of polishing in a few places, I decided to try the set.
The mainspring has a 'V' cross-section, the trigger return springs come in a set of reduced power, 13, 14, and 15 pound springs. The mainspring can be had in full factory power or a reduced, I chose factory for it; the trigger return I started with 13 pound.

Warning: if you don't know how to change these, or start farting around inside the action, get help. You have been told.
The inside was nice and clean, so other than change these two parts all I did was put a few drops of oil in places, and reassemble, then try the action.
Holy crap.
I would not have believed that those two springs would not just lighten, but smooth the action that much. Did some dry firing, and soon as time allowed put some ammo through it.

Worth every penny.

Indeed. Have used Wolff springs more than once in the past. FYI for the audience regarding S&W revolvers--do NOT pry the side plate away from the frame. Tap the frame with a soft hammer and let the side plate vibrate out on its own. Plenty of videos out there showing how to do this.
ReplyDeleteOn my own M67, the mainspring is flat, and
adjusting the hammer tension screw was sufficient. For the trigger, I shortened the stock return spring two coils. Keep in mind that If S&W gets so much as a whiff that you tinkered inside the gun, any warranty just went up in smoke.

To polish the action, slather it with whitening toothpaste, re-assemble, and cycle it a few hundred times.
I second the motion.
ReplyDeleteI've used Wolff gunsprings on various guns of various types at various times and I've always been extremely pleased with the quality and workmanship of their products.
