Question for you that have shot the SP101 and the GP100 in .22LR

I really hate how stiff the action is on my SP101 even with polishing and lighter springs.
I believe the dimensions of the GP100 may make for a better action and easier hammer pull.
Seems like the larger hammer would wack the primers with more leverage!
Would it be worth selling the SP101 to purchase a GP100 .22LR?
Tell me your experience!

I have an SP101 DAO in .357 that I performed a trigger job on. I replaced both the hammer and trigger springs. I also added hammer shims to center the hammer. I finger turned a drill bit thru the trigger spring channel and used a little bit of compressed air. I didn't polish anything and did nothing else to the internals other than wiping things down.

That being said...the trigger action TO ME is buttery smooth. It has a comfortable pull and easily allows me to stage the hammer for a glass smooth transition into the trigger portion of the pull.

I also own a pair of LCR's..one in .357 and the other in .22WMR. The trigger pull on the .22WMR is inherently heavier than that of the .357. Part of it being a rimfire which requires a stouter spring to smash the primer and the other part of it being a smaller frame gun with a shorter fulcrum. I believe any engineer would tell me it takes more effort to use a shorter fulcrum than it does a longer one.

So, your statement has merit. If I were you...and was not satisfied with the pull after all the work that has been done on it...I would SELL it and go with a GP100.

I like my SP101 22. Swapped springs and l like the trigger now, though it isn't my SP101 WC. I bought it for a plinker and to hike with, and the GP is just too heavy for hiking. If I only used on the range, I might go GP.

I do like the size and weight of the SP101.
The GP100 weighs 12 oz. more!

I think that you would really like the GP over the SP.

I am waiting for my SP to come back from Ruger. As soon as I receive it I will reinstall my shims and lighter springs but move up to the 14# because too many FTF's shooting SA.
I'll give it another try, but I am going to stop and take a look at the GP100!

My SP101 has Wolff 10# springs in it...and it's smooth! Can't be a Wolff Spring after some light sanding and polishing to smooth things out!

That being said...you can't beat a nice GP100 when shooting .357's either...I really like mine!

Some thoughts. I have centerfire SP101s and GP100s. With the 8 lb trigger return and 9 lb hammer springs, due to leverage the GP is about 1 lb. lighter in double action and slightly lighter than the SP in single. Somewhere on this board I believe Iowegan acquired a GP 22 and tuned it. I forget what mainspring he used but think it was either an 11 or 12 pounder. Given that I would expect the GP to be about 2 lbs or a bit more lighter in double action than your SP with the 14 mainspring.

As I have mentioned elsewhere gun weight also gives a perceived feel in trigger pull also. Two guns with the same trigger pull but different in weight, the heavier gun will feel lighter. A Redhawk with a 10.5 lb pull will feel lighter than and SP101 with the same pull due to the tension in the hand to support the additional weight.

Ah, here is the link to Iowegan and his GP22 string. His post is down a ways:

SP101 or GP100?

I've had an SP101 .22, the quality was good but found right away that the wide frame and small grip made it unusable for my hands. I couldn't pull the trigger without the tip of my finger pressing into the frame before it would fire. I didn't bother changing grips or springs, just sold it.

I have a few Rugers but many more S&W's. I wanted to try the GP100 .22 to see how it compared. The trigger pull when new was no better than the SP101 but it fits my hand much better. After a lot of work, the GP 100 is now a good shooter. I especially like how smooth the trigger return is compared to S&W's, but the S&W's seem to be easier to get a lighter pull. The GP also has a longer DA trigger pull than my S&W 617's.

The GP is a big beast if you plan to holster it for hiking. But for a range gun and if you want to stick with Ruger, the GP may be a better choice than the SP101.

Since I prefer S&W's for the fitting to my hand my choice for hiking/woods carry would be the S&W 63 and the S&W 617's for competition and range plinking.

My reworked GP100 .22 is working great now but it has yet to prove itself in competition (I haven't had a chance to compete with it yet). I expect it to be very good especially with farther targets because the extra weight makes it very stable.

Here's another story on the SP101, 22lr. My double action was fine out of the box,but single action was too hard to cock. I over oiled and cocked the hammer numerous times and it finally smoothed up,now it is fine. All I did was put a Hogue 81000 rubber grip,to fit my hand better.This was before the GP100 came out in 51/2 in. bbl. I found the GP100 too heavy and I have not held/seen a 4.2 in. bbl. GP100. I find as a plinker/woods pistol that 8 rds. is enough,I do not need 10. I am very pleased with my pistol and feel no need to add/change anything.I also did not have to move my sights.I am wondering if I am the only one happy with their SP101 out of the box?

Ok if I am reading this correctly or understanding whats been said, the OP has a SP101 .22LR & isn't happy with the trigger pull?? So now thinking of shelling out the $$ to get a Ruger GP100 .22LR??? The very basic design's between the GP100 vs the SP101 the SP101 will always have a stiffer trigger pull and action no matter if its centerfire or rimfire. The rimfire requires heavier springs to ignite a rimfire ctg. like the .22LR If you have played the spring jobs and now it sounds like Ruger CS has it?? Not sure what to tell you, sounds like you are trying to be patient to wait things out and hope for the best. The SP101 .22LR's yes have a big history of heavy actions & trigger pulls. I guess you hope that with usage things will settle down or yes look for something else! I do wish you the best of luck I guess I am lucky my S&W Model 17 .22 LR has a very nice action to it but this is a different design! Not better just different.

This makes alot of sense to me!
I do like the size and weight of the SP.
