A serious guestion about a little Creep!

I have a new model SP101 .22LR.
I have polished the insides with Mother's, including the seer, being careful not to remove any metal other than by polishing!
I installed the shim kit and the new Wolff #17114 spring kit for the post 2011 .22LR. I installed the 8# trigger spring and the 13# hammer spring.
Since then, I have dry fired it some with yellow wall anchors and shot close to 1000 rounds through it.
In DA the action feels fairly light, smooth and really great!
Single Action is where my question is. It is as light as it can be to have reliable ignition and seems smooth.
But if I am paying close attention, sometimes I can feel a little trigger movement prior to the seer disengagement. I would assume this would be "trigger creep"?
I don't know how to change this without removing metal and changing the hammer hook, which I'm not comfortable in doing.
I think I would be better off with a controlled trigger pull with a little feel than than one that goes off almost as a surprise! My wife will also be using this gun for snake control, I want to be on the safe side
Give me some input and let me know your experience! Any suggestions?

Leave it alone. You've already done more than it needed.

jalopiejoe, The feeling of movement in a trigger is called creep. The amount of tension on the sear is proportional to the amount of creep. Oddly enough, you will feel more creep in a light trigger compared to a heavier trigger pull. You can reduce the amount of felt creep by reinstalling the factory springs, however this will also increase trigger pull weight. I think blackvoid summed it up quite well.

Here is more discussion mainly on the DA part of revolver but also on buffing the single action notch:

GP100 sear/hammer engagment questions (trigger job stuff)

Also, as you note you probably don't want to remove any metal i.e. reduce the depth of the single action notch as one can get pushoff which is dangerous.

jalopiejoe, Like was already mentioned, I would leave it alone. Incidentally using .22 snake shot out here on the Mohave Green Rattlers just seem to piss them off, myself I like at least the .38, or preferably the .44SPL. Note you only shoot them as a last resort, I know they can become very aggressive when out hiking thru our deserts out here.

There are lots and lots of posts about the SP101 trigger.

DA can be 15lb or greater. Designed by lawyers.
SA can be 8lb or greater.

Mine was gritty and it stacked badly.

After 40 hours of custom action work, I have mine reasonable.

There is an absolute grand canyon type chasm between SP101 owners. It appears obvious that some are very nice and some are not.

Treat yours accordingly.

I probably shouldn't, but tomorrow I am thinking of pulling the hammer and trigger group and polish it like chrome!

Keep in mind that while you can slowly close in on "just right", the distance between "just right" and "way too much" is really, really short!

At this point you're probably in the camp of "leave well enough alone".

Sometimes a tiny dab of white lithium grease on the engagement surfaces can help with that creep.

Last night I pulled the hammer and trigger group and polished the seer till it shined and used thicker shims to remove the side play.
Then I polished hammer hook and area till it shined then added shims (.008) each side to remove slop and center the hammer.
Now the action is Very smooth and there is No discernible creep. A good solid engagement and crisp break!
I believe the action is as good as as it can be.
I am very pleased with it now and it is time to enjoy it and Leave It Alone!!

I would dare say that after reworking my 2013 SP101 22LR this last time (and I mean last time) the trigger is every bit as nice and smooth as a Smith and Wesson model 617 (with an action job) I compared it to.
I don't think there is anything else I could do to it!
I still wish the hammer spring could be lighter but anything else is not reliable.
I'm finally Happy with it! ??

Good for you, bud.

It shouldn't have to be done, but thank god, Ruger made it possible to do yourself.

A good trigger is essential to bonding with a firearm. It sounds like you've got a new sweetheart you need to take dancing.

It is a good thing that Ruger's are fairly easy to work on and I've spent alot of time with this one.
Now it's time to quit while I'm ahead!
Yes, I do have a new sweetheart and Yes, we are going dancing!!!!

I went to the Ben Avery shooting range today and shot another 300 rounds.
Very pleased how the gun functions but I did have a few FTF's when shooting DA!
I was using Winchester 555 bulk pack, 36 grain copper plated hollow point. I believe it to be good quality, but I don't know for sure.
Next I'm going to try Federal 325 value pack. Same bullet.
See what happens with that brand.
I don't really want to change the 13# hammer spring.
I know everyone says use CCI for reliability but I like bulk pricing!
