wc gp100 vs. regular gp100 vs. sp101 triggers

this past weekend, i fired a brand new 3" wc gp100, the trigger felt good. i then fired a brand new 6" gp100, and the trigger also felt good.

i bought a gp100 new about 15 years ago and sold it about 4 years ago. i bought a sp101 about 8 months ago and the trigger is just like i remember my old gp100. heavy and gritty.

are the pull weights on sp101's, standard gp100's and wc gp100's the same or are they different? are new guns pull weights the same as the old models?

maybe its all in my head...

I've found a range of trigger feel across the GP100 and SP101 guns I have. I've found metal shavings and tiny metal chunks in more than one trigger group. I had a really gritty trigger return on an SP101 that was 18 years old (I bought it used) and found a chunk of metal inside the trigger return spring. It had probably been there the past 18 years and the previous owner just lived with it. All of these guns seem to benefit to some extent with a bit of trigger work, either a DIY project or by a gunsmith. If you find one you like right out of the box then you did well. But if not it can probably be improved to a level you can be happy with.

I think the WC GP100 has the same mainspring and trigger return spring as any other GP100. The SP101 uses a different size set of springs due to the smaller frame but Ruger may be designing to the same pull weight. Ruger doesn't disclose this information to my knowledge so I'm really guessing at this point. I usually end up running reduced power spings in my GP100 and SP101 from Wolff because I like lighter springs but there is also a distinction between light pull/return and smooth pull/return. A shooter may want a heavy pull in a personal defense gun for guranteed ignition and to prevent accidental discharge when the adrenalin is flowing. But you still want a smooth action with no grittiness, hesitation, or a hitch along the way. So when you break it down it becomes two separate issues.

I'm no gunsmith and there are others here more qualified to answer your questions than I am. But I don't think your observations are all in your head. There are normal inconsistencies among standard production examples. They're not custom guns carefully hand-tuned by a master gunsmith - that costs extra.....

My experience is that the GP (I have a 6") is lighter than the SP (2" and 4" 22lr). I like 'em all, but the SP takes more effort stock.

Ruger triggers

I've completed numerous trigger jobs on S&W J,K,& L frames, as well as several SP101s. The Rugers show much more dramatic and positive results than the Smiths ( due to the fact that a Smiths trigger is better out of the box.). The Ruger triggers can be made just as fine and smooth as a Smith with a trigger job. However, due to the geometry and design of the trigger return ( rebound ), the Ruger return will not be as smooth as a Smith.

I own three SP 101's only one had a decent trigger from the factory the other 2 IMO needed work and are fine now .My GP while not bad was also worked on and now is as smooth as my Colts .I haven't really seen any poor/bad examples with the GP line but Ruger needs to give the SP line a little more attention ,overall though they are great revolvers.

I feel the GP has a better trigger than an SP out of the box because of the geometry. The SP is not a scaled down GP. The shape is different. The SP is flatter or more rectangular if that makes sense. I think that makes the two very different.

All other things being equal a medium frame revolver such as a GP, K frame Smith, etc. will have a lighter trigger than a small frame due to having increased leverage in the design. Also, some have claimed a few years ago in the GP that Ruger went to a lower weight spring for the trigger return which would be logical due to the increased leverage vis-a-vis the SP. In my SP and GP when both have a 9 lb hammer and a 8 lb trigger return spring in them the double action is 8.4 lbs in the SP and about 7.4-7.5 in the GP as a comparison. Normally, I run a 10 lb mainspring in the SP. Others have claimed the Wiley Clapp gun receives the same treatment as the normal GP's. A SP can be made quite smooth but will never feel quite the same as the GP due to leverage, mass of the parts and such. All this is not unique to Ruger but also applies to S&W, Colt, etc.

I had gp 100's 3 to 6 inch barrels and sp101 3 and 4 inch 357's between current year and about 10 years old. each had a different trigger feel. It did seem like the newer trigger felt better out of the box. Still all ended up with about the same feel with a quick polish of the trigger internals and wolff reduce spring kit. I would go out and shot about 100 rounds then one more polishing and they were nice and slick. remember polish means that to make shine and some what smooth...not taking any metal off nor changing any geometry. I used Flitz polish and felt tips with my dremmel.

The most dramatic difference was my redhawk. I hated to even pull the trigger as it felt like the trigger components were simply grinding against each other. I polished it..lubed it ...shot it... then polished it again. Now it is the standard that I go for with each new security six I get. (I found that I preferred the security six to the gp 100 or sp101). That is not to say that the six's I have found need much work but I wanted try to achieve a standard trigger pull across the board with all my revolvers.

slick smooth DA pull with no hitches.

I don't have a GP, but my SP did need some work. The Wolff spring kit is the Cat's Pajamas. I replaced the 14 and 10 pound with an 10 and 8. Man what a difference. It's right up there with my Redhawk now.
(BTW: "Cat's Pajamas" is a good thing ).

I have a SS GP100 (4-inch) that I bought new in the early '80s. It has the original wood grips and had a very smooth trigger pull out of the box, so I've never done anything with it but shoot it. I liked it so much that when I wanted a small pistol to conceal, I went with a new LC9. Sure wish the pistol had as nice a trigger pull as the revolver! Still, after using those two handguns and two Ruger 77Rs (.270 and .308 tang safety models - wish I still had them) whthout any problems at all, I think I'll pick up a new SR9. IT's nice to see quality, American-made products out there!

I owned 4 different GP100 revolvers over the past 20 some years. The most recent is a stainless GP100 with 5" bbl that I bought some 2 years ago, and it had the best out of the box trigger pull of all of them by a significant margin. I did a spring change and polishing to improve it a little, but it really wasn't needed that much. I also owned an sp101 that I could never approach the trigger pull of a GP100 primarily because of the different geometry and leverage as others have previously noted.
