View Full Version : What's your revolver trigger weight?

Have you tested your trigger pull weight? What is in your opinion the ideal number?

While adding a spring kit to a new "Chief's Special" (my post about that is here (http://www.calguns.net/calgunforum/showthread.php?t=1161984)), I tested the following revolvers with a set of RCBS trigger pull scales.

DA lbs, BRAND & MODEL
09.50, Smith 36-10 (with Apex spring kit)
09.75, Ruger LCR
10.00, Ruger LCR-357
10.00, Smith 14-4 (1977)
10.00, Smith 17-8 (1993)
10.50, Smith 27-2 (1965)
10.75, Smith 586-8
11.00, Smith 586-7 L-Comp
11.50, Smith 36-10 (before Apex spring kit)
11.75, Ruger LCR-22
13.00, Smith 27-9

and here they are in single action...
SA lbs, BRAND & MODEL
2 lb 2 oz, Smith 36-10 (before & after Apex kit)
2 lb 8 oz, Smith 27-2 (1965)
3 lb 0 oz, Smith 586-8
3 lb 2 oz, Smith 14-4 (1977)
3 lb 8 oz, Colt SAA (1977)
3 lb 12 oz, Smith 17-8 (1993)
4 lb 0 oz, Smith 27-9
5 lb 2 oz, Smith 586-7 L-Comp

I find I'm comfortable with anything under 11 lbs, but prefer the smaller guns lighter. I'm not the original owner of the three oldest Smiths in the list, so I don't know if they've had work done or were just "well-loved" to that point, but 9 or 10 pounds double action is what was recommended for duty guns back in the day. Any lower than that is a goal for a specially modified competition gun that is probably unsafe for other uses. Comments?

Measured with a Lyman Electronic Digital Trigger Pull Gauge:

S&W 627 PC (Single Action) | 4.06# | 2.4 Std Dev
S&W 627 PC (Double Action) | 10.42# | 1.53 Std Dev
S&W 686 SSR (Single Action) | 4.43# | 0.98 Std Dev
S&W 686 SSR (Double Action) | 11.08# | 1.99 Std Dev
S&W 629 Classic (Single Action) | 4.27# | 1.41 Std Dev
S&W 629 Classic (Double Action) OFF the chart (> 12#)

I am the most accurate with my 627 Performance Center in double action. 14.6gr of 2400 behind a 140gr HP-XTP. Just like a tack driver! I shoot my 357 revolvers in double action for 100 rounds. I only shoot the 629 in single action for the obvious reason. Finger can't handle > 12 1bs for very long.

Are your high standard deviations due to low n or big variances? 2.4 is pretty big.

Both of these have had action jobs by Randy and the guys at Apex Tactical. I'll admit I don't have the longest history with revolvers but the actions on these wheel guns are very smooth and predictable.

HFW=Hammer fall weight, TPW=Total pull weight

S&W 586L-Comp: HFW@2lbs15oz., SA TPW@4lbs10oz., DA TPW@9lbs4oz
S&W 386PD: HFW@2lbs11oz., SA TPW@3lbs13oz., DA TPW@9lbs2oz

Dunno. The data is what I got using the tool as described in the users manual. What should be the maximum?

I don't know I've never removed it from the gun and weighed it!!

To answer your second question.

929 S&W with serious mods for USPSA Revolver Division. I had the single action removed and the double action is right around 5 lbs. average. Yes I have to use Federal primers. I could get it lower but I like the feel of a little heavier rebound spring.

Have you tested your trigger pull weight? What is in your opinion the ideal number?I always set my revos up for about 6 - 7# DA pull and about 3# SA pull.

Interesting. Do you replace the firing pins and/or use handloads?

Spring Kits? Yeah, I know there are a lot of guys who buy reduced weight spring kits, install them in their guns, and call it a trigger job.

THAT IS NOT A TRIGGER JOB!

Lighter hammer springs are nothing but trouble. Slower lock times, lighter primers hits, none of which is a good thing.

Buy some stones, learn what and where to polish, reduce friction between metal, and be proud you did a proper trigger job.

I have tested the "extended" firing pins and determined they do absolutely nothing to improve ignition in guns assuming the firing pin in the gun is not defective. They are prone to breaking, so I never use them (anymore).

I set the mainspring force to whatever I need to light my ammo which is just factory cheap stuff like S+B or Winchester. I adjust the rebound spring to give good trigger return. I also polish the internals and the DA pull usually ends up being between 6 and 7# after all that.

Good points, but in this case I couldn't have shaved 2 pounds off my m36 trigger pull just by polishing. I did polish the rebound slide while I was in there, but the goal here was to get a pull like a Ruger LCR or Kimber K6. (So why didn't I just buy one of those instead of a Smith classic style snubbie? Different discussion.)

I have a Ruger GP100 from Gemini Customs. Double action is about 7 lbs and smooth as butter. Single action is around 2lbs. As much as I love 1911's, my Gemini Custom GP100 is my favorite handgun.

I have no way of measuring pull weight , but my ruger hunter feels like around low 2lbs ish . I think previous owner did some minor work on it . there's no way it around 5lbs factory

Thanks for the pics! My 586-8 is 3 lb SA, 10.75 lb DA. Did you or someone else do any work on your 586? In fact they all have great numbers. Do they shoot reliably?

I did my own work on the 586. 100% reliable.

The S&W 625 I use at the local shooting fun match:

8lb 14oz DA 2lb 5oz SA

I can shoot it nearly as well DA as SA. If it's set much under that for DA I start getting occasional light primer strikes with Winchester (hard) primers in .45 auto rim brass.

Thanks, would love to know exactly what you did. I dropped a third-party spring and pin kit into my Model 36 with only a little bit of polishing on the rebound slide, and am not happy with the results: http://www.calguns.net/calgunforum/showthread.php?p=17792444#post17792444

Using a cheapie trigger pull gauge that tops out at 11 pounds, so take these values for what they are:


S&W 500 (3lb 8oz - 11lb)
Colt Anaconda (3lb 4oz - 11+lb)
Colt King Cobra (2lb 8oz - 9lb 8oz)
S&W 686 6 inch (3lb 4oz - 10lb 8oz)
S&W 686 8 inch (3lb 8oz - 11+lb)
S&W 29-3 (3lb - 10lb)
Chiappa Rhino 200DS (2lb 8oz - 10lb)
Ruger LCR 22 WMR (11+lb)

I tooK it apart and went part by part. Basically feeling for grit when replacing parts in. I polished the rebound slide and the frame area it glides on, rebound slide to hammer contact, trigger to cylinder lock, cylinder arm contact areas, etc... basically none of the surfaces that are important to proper working and all of the surfaces where two parts are rubbing against each other.

My 586 has a bunch of min parts and I couldn't get it to feel any better, but right now the trigger feels smooth and you still hear the various parts contacting each other as you pull.

I did use the low weight hammer spring and rebound spring. I had to bend the low weight hammer spring to increase tension. As it was, I couldnt get any decent tension on it with the tensioning screw.

I only own single action revolvers. I work the internals til I get:

~3 lb at the top of the trigger
<1.75 lb at the bottom of the trigger

Creep is inevitable, but if I get it shiny enough to see myself, I can't feel it.

My safety is "Don't pull the hammer back 'till it's time to go"

Nice thing about SA....

That is a beautiful K-22!

Below is a new Model 36-10, fresh out-of-the-box: 3 lbs 2 oz SA, 13.5 lbs DA! Wow, that's even heavier than the previous one, which was 2 lbs 2 oz SA, 11.5 lbs DA.

I know this isn't a Performance Center gun, but you'd think the out-of-the-box double action pulls on these two guns would be within one pound of each other, not two pounds. Dry firing a couple hundred times works out kinks but does not change the pull weight.

This may be yet another candidate for an Apex spring kit, plus possibly more part polishing than usual. (Then I'd feed it only high quality ammo that will be reliable after the lighter springs are installed.) It definitely needs a Pachmayr Compac grip, love those.

Pretty sure my Charter Undercover Lite had a DA pull was around 14 lbs, single was clean and probably 4 or 5. I got the DAO hammer for it, and now it's easily two pounds lighter, and smoother.
