After owning several GP100s I purchased a new SP101 .357 in June and after the first 50 rounds of .38 Spl. I was convinced that the revolver was a POS, due to the heavy trigger pull and wondered why Ruger made such junk. After a lot of dry firing, and about 250 rounds, the trigger is much improved and I think that a set of springs will make it a keeper.

Shims, springs and a little polishing. Follow the turorial mentioned above and be very careful not to launch the pawl spring and plunger as I did. I used Mothers mag wheel polish. It does not take much. Lance recommends the 12# mainspring (stock is 14#) and the 8# trigger return spring. You should be able to use the stock 10# return spring to ensure trigger resets (doesn't seem to be an issue with the 8# Wolff spring though).

I put the Wolff springs in mine and it seems to decrease the pull to about half of what the factory sent me. In fact....the factory pull was HORRIBLE!

I don't think the factory pull was horrible but I did install the Wolff 9# spring. That plus a gunsmith's trigger job got the DA pull down to 7.5 lbs... and no light strikes in over 2 years. Money well spent.

Having a gunsmith smooth out an Sp101 is not expensive. I had my SP101 worked over for $80 including parts. When a gunsmith works over a gun they do things that you cannot do at home. A real gunsmith will have a machine that does nothing but shape hammers. You want to have the hammer cut down so it has a shallow notch for the sear. Cutting the hammer will not make your gun unsafe. Ruger cuts the notch in the hammer to deep for the gun to perform smoothly. Ruger wants to cover their ***. He will fit the sear to the hammer. He will make sure your cylinders are uniform and cut the out to make reloading the gun very easy. The forcing cone usually needs to be opened up and he make certain that everything is straight, some people call this blueprinting.

Here is a basic layout of what a gunsmith will do. This is for a single action but the process is very similar. Accurizing the Ruger Single-Action Revolver

I followed the instructions to this SP101 Trigger web page and put in different springs; I haven't seen my revolver since my wife took it and made it hers... BTW she completely took it apart to clean it and put it back together following the instructions and she has NO experience w/disassembling firearms before this

This method uses oil and high grit wet sand paper (2 & 3K) to polish the innards.

So after finding this thread on a Google search titled "heavy trigger pull SP101" I discovered I wasn't the only one who hated the ridiculously heavy trigger pull that this gun came with. I read through the thread and immediately went to Midway and ordered the Wolff spring kit. Thanks to everyone who posted and got me on the right track.

Since my 2-1/4" .357 was in the process of undergoing a let's not clean it for a while test and see how she does, I took the opportunity while camping this weekend to disassemble Mr. Shorty and not only clean it but swap the springs. Really easy and a big difference. I chose to just go straight to the lightest pull right off the bat. Personally I love a light trigger. I installed the Wolff 8# trigger return and 9# hammer spring.

I've had this pistol for about 1 year or less and it's been a love hate relationship. I love the fact it's built like a tank, chambered in .357, and easy to conceal, but I've hated the heavy trigger and the fact I have struggled so much with putting rounds right where I want them. After the lighter spring installation I shot 39 rounds through it with good shot placement, not perfect yet, I have a feeling it's just me and the fact this thing is so short, plus I only practice with .357 now, no 38.spl anymore since I carry with .357 Magnum.

I did have ONE light strike during my 39 rounds and the gun didn't fire. The dent in the primer was obviously light when I looked at it. Today I compared the primer strikes from the lighter trigger to other casings prior to the swap, and they all looked pretty identical. I'll be shooting more with the light springs and I will report back. I really don't want to swap up the 10# hammer spring, but if I get more light strikes I'll most likely have to give it a try.

I should also note, I have quite a few rounds through this gun, I've been meaning to count my spent casings to find out exactly how many, and I did do the trigger job immediately when I brought this gun home. I found the info online, which is really just a light sand on the part of the hammer or whatever, it's been a while I'd have to have it apart to remember exactly what I sanded.

*sorry for the long post*

I don't know about the edit feature but for other features some require 10 posts so you are getting close.

I have a SP and it runs now with the 9 lb mainspring and 8 lb trigger return (I had the 10 lb mainspring in it for a while). One other thing to look at that might decrease any fail to fires is firing pin protrusion. On the forum elsewhere Iowegan discusses how to address this by taking a little bit of metal off the top of the hammer where it rests against the frame. There are other things that can help also but a bit more involved.

I've been told it's the geometry of the mechanics. However I am going to polish mine up again tonight. I did it last week and changed the springs to 10# hammer and 8# trigger. Trigger return was iffy so I put the 10# spring back in. Had 3 light strikes in 250 rounds so I put the 12# hammer spring in and there is a world of difference between it and the 10. Going to republish everything tonight and barely touch the hammer spring hole with 1500 wet and dry then out back the 10# and 8# springs and run 250 more rounds this weekend. All the light strikes went off the second time. I may use the hammer filing method too. Once I get past the initial movement, it's pretty smooth, it's the first 1/16 to 1/8 inch that tough.

Made the spring changes and polishing last night. Haven't had a chance to shoot for reliability, but if dry firing is any indication, this trigger is going to be awesome. Followed the directions on the link, and the advice of sanding the hammer. I used 1500 wet and dry on the hammer using a drill press table as a guide. The hammer is not even close to flat from the factory.

I do not understand at all why you want to attempt to do this yourself, especially if you have never done an action job before. Do you at least have experience with metal polishing? Are you just trying to save money? Not worth it if you mess up your gun, or even worse... render it less safe. Action jobs are an art form. And it is not that expensive. On top of that, a good gunsmith can do wonders with an SP101. Some guns respond better to action jobs than others, and the SP101 is one of the guns that responds best of all.

Save something from your next few paychecks and let a pro do it. It shouldn't be more than $200 anywhere in the country, unless your gunsmith is famous. Probably closer to $100. Combine that with lighter springs, and you'll be shocked how good the SP101 trigger can be.

On the opposite end of the spectrum, why not do your own action job? Spend some time watching videos, reading guides, and asking questions. Get familiar with the internals of your firearm and go slow. Small adjustments with repeatable testing. You might mess something up and need to send it back to Ruger (where they may charge you for replacement parts), but you gain a lot of knowledge and the ability to troubleshoot any future issues much more thoroughly. I agree that it is an art form, but there's no reason you too can't learn it.

Well let's see. One of my best friends has a background in robotics, I used to earn my living as a machinist, I have been shooting and doing most of my own work and picking the brains of others, for almost 40 years, the people on this forum have given invaluable advice regarding many issues and are proving themselves to be a most valuable resource, if there is an issue with my gun I don't have to wait weeks for someone else to do something I can easily do myself or with my friends, and I know exactly how my guns work and what makes them tick. So as a result, I have an SP101 that is as slick as any you might find anywhere, functions perfectly, is able to eat the center out of a target at self defense ranges (the exact and only purpose of my SP as I have other tools for other purposes), and I have the money that others would spend letting someone else do there work to by bullets. By the way, took it to the range today and put 100 rounds of 357 and 200 rounds of +P 38s through it. All reloads by the way as I also refuse to let others make my ammunition. Every single one went off. No light primer strikes, no hitches, no nothing except bang 5 times in a row with each cylinder of ammunition. This is with the action job and spring changes mentioned before. I think it'll do, and I think I will continue to do my own work, along with my friends.

First, you have a machinist background. Most people attempting a trigger job have never worked metal before, and I know many who have never even sharpened a knife, polished a handlebar, or anything else that involves any sort of metal abrasion. You really think it's a good idea for such people to try their hand at fundamentally altering tiny moving components in their guns' actions, if they've never so much as handled a sharpening hone or stone before?

Second, there are the the potential consequences of doing it wrong. We're dealing with thousandths of an inch here. Get the wrong angle or too much material removed from the sear or disconnector, and suddenly you've got an unsafe gun on your hands.

No thanks. You keep tinkering. I'll take my guns to a professional gunsmith, preferably one who is factory-trained and authorized. And if I ever do attempt my own trigger job, it will only be after receiving formal training. I may go that route in the future.

That's ok. You do you and I'll do me. Everyone has to learn how to do something at some point in their lives. I made it a point to learn at an early age. The people I've always associated with have minds like I do. Between myself, and the very few people I call my friends, there has been nothing so far we couldn't fix, make better, or figure out it works.

A side note, the people who frequent this forum are very smart. Not me, but I gp have gotten a few tips from people on here who have guided me towards directions regarding my firearms that have saved me hundreds of dollars, just by doing a few simple little things.
