Just got my new Wolff spring kit in today. They finally came out with a spring kit for the 2011 and later SP101 22 revolvers. The factory springs are a bit stiff. This is the first time I have done a trigger job of a revolver.....I will post the progress and some range reports as soon as possible.....

I will be waiting to see how this turns out. I bought a 22 Sp101 Jan. 7 and it had a 15+ lb double action trigger pull. I cut a coil and a half off the hammer spring, and smoothed up the hammer strut. Cut one coil off the trigger return spring, but it needs a little more. I ended up with a 11 lb double action trigger pull, and 3.5 single action, which I never use. I have ran thousands of rounds through it, so its well broken in. I do get a FTF sometimes with some ammo but that is pretty much poor ammo, or shell not complety seated in dirty chamber. I have been shooting Winchester 22-M which carbons up the chambers in a hurry. Have to run with what you can find.
DO NOT PULL THE TRIGGER WHEN THE TRIGGER ASSEMBLY IT OUT OF THE FRAME...
Keep us posted.

Sounds good mark.....the factory trigger spring is 10 lb and the hammer spring is 16 lb. I am going to go with the 8 lb trigger and the 14 lb hammer spring. From what I have read so far.....if you go to light you will get miss fires....I plan doing it this weekend, I will take a few pics along the way....

Well I installed the Wolff spring kit in my SP101 22. Here are a few pics and some of the stuff I did along the way....First I disassembled the gun and laid everything out.

Then I removed the trigger spring. It was pretty easy to do. Just push in the plunger cap and push out the pin. There is only one trigger spring that came in the kit. The factory one is a 10 lb spring, and the Wolff spring is a 8 lb spring. Just make sure the flat spot on the plunger cap is up so the pin can go back in....

Then next is to change out the hammer spring. This was the part that was kind of a pain in the butt. Push down on the hook/catch and pull out your take down pin. The hammer bar is a stamped piece of metal with ruff edges. I took 400 sandpaper and smoothed the bar out. I removed all of the stamping marks on the sides. Then I took 600 sandpaper and made everything super smooth. I seen the done on line, it stated that the smoother the bar is the easier the hook and spring can move on them. Now putting it back together.....Make sure the hook and bar are in the same position....lay them out the same way they were removed. The factory spring is 16 lb, the kit comes with a 13, 14 and 15 lb spring. I used the 14 lb spring. Then I took a paper towel and folded it up to push down on the hook/catch. Put the take down pin back in and your done.

I put the gun back together and WOW.....what a difference. The trigger is very, very smooth. It is quick and very snappy. It feels great....this kit is a must have for anybody with a 2011 and later SP101 22. I am going to try to get to the range this week and try it out. I didn't use the 13 lb spring because from what I have read on the inner web, is that too light of a spring will cause miss fires. To me the 14 lb spring feels perfect. I will post a range report as soon as possible......

Biker, great post. Great to know that they finally came out with this kit.

Main issue besides the better trigger pull is whether you experience light strikes. Let us know.

Found it at the Wolff web site and ordered it.

Keep us posted. I have the same gun: late model (2013) SP101 .22LR. I love the gun but if I could lighten the trigger a bit without sacrificing reliability (i.e. light strikes) I would do it.

Installing the springs myself is possibly beyond my technical skills. May have a trusted Smith do it. Thoughts on that?

Great post!

Thanks so much Redleg......It really was a pretty easy install. I got on youtube and watched a few videos. If you field strip your gun to clean it.....you can do this trigger kit yourself. I spent more time sanding on the hammer bar than anything else. I am just like you...if I could lighten up the trigger without getting miss fires, I was going to do it. I wish I had a way to test trigger pull. But right now with the new springs in, it feels 100% better. If everything goes well.....I may be able to sneak to the range tomorrow for a little testing. I will let you know how it goes. Again thanks....

Biker..looking good. After reading your first post that Wolff now had springs for that gun I couldn't wait, ordered some.

Redleg...Its pretty easy. Just do it someplace where if something gets away from you, you can find it.
AND, as I said before, don't pull the trigger when the gun is apart.

I'll watch the You-Tube video and see what I decide. I am pretty bold about field-stripping semi-auto pistols (I am very good with the Mark pistols and 1911s, for example) but I am a complete coward when it comes to revolvers, which I never have taken apart beyond replacing grips.

I and others will by VERY interested in your range report -- whether the lighter springs produce any light strikes. I'm guessing not -- Wolff usually knows what they are doing.

Well I made it to the range today. I ran around 200 rounds through the gun. I used three different brands of 22 ammo. I had no miss fires or light strikes at all. But I did run into this, with the 8 lb trigger spring, the trigger hung up about three or four times. It was not that bad...but did get on my nerves a few times. So I installed the factory 10 lb trigger spring back in and left the 14 lb hammer spring. Well with the 10 lb trigger spring, the trigger is not super smooth like the 8 lb spring was. It didn't hang up any more but now it only feels a little better that the factory springs.....I am going to try a few more things.....I will keep every one posted that is looking at this post.....

I really appreciate the posts and experience with this spring dilemma.
I looking forward to rewarding more about this. Nice job again biker

Biker....
When I took my trigger spring out and cut off one coil, I turned a quarter inch drill bit in the spring hole by hand to make sure it was smooth and there was nothing to catch the spring. Also you might make sure the transfer bar is smooth where it rubs against anything. When you release the trigger the transfer bar has to slide down from between the hammer and the firing pin?frame. I keep a little oil on the transfer bar, and being I shoot double action, some lube on the hammer strut. I am betting that if you get things all smoothed out, the 8# trigger spring will work.
