Revolver With Lowest DA Trigger Pull?

I don’t know what is lightest but the LCR has a lighter pull than the 101.
The recoil is substantially more and could be a bigger problem with your arthritis.

A Kimber K6S or the aforementioned Ruger LCR will likely be your best bet for off the shelf triggers.

Ruger's are easy to work on.

my Security Six had about 6-8 hours invested in polishing parts with water-stones and fine, and extra fine diamond compound and it now pulls smoothly and evenly at 9 pounds.

You could replace the Hammer Spring.

I replaced my GP-100 using Wolf Springs. Very simple and easy to do with YouTube.

"factory hammer spring is 14 Lb.."

They offer a 9# spring for less than $5.00.

If you have shot the gun or dry fired a lot you have probably married the internal parts and they are pretty smooth.

I believe Midway USA & Brownells also sell them.

What 357 Magnum or 38+P revolver has the lowest DA trigger pull?

I read somewhere that the new Colt Cobra has a factory rated DA trigger pull weight between 7 and 9 pounds. I know the one I handled a while back had a DA trigger pull that was significantly lighter that the j-frame Smith I've been carrying for years, and it was a lot smoother to boot.
The only reason I didn't come home with that little Colt is because it weighed more than my j-frame Smith. I wasn't sure the better (lighter and smoother, both DA and SA) trigger made up for the extra weight I'd be carrying.
I still might end up with a Colt Cobra though. I'm still tempted, and I don't even have arthritis in my trigger finger (yet). Come to think of it, the extra weight of the Colt Cobra over my j-frame Smith might be easier on my arthritic wrist.
How about that? I think I've talked myself into buying a Colt Cobra!

Just be careful that you don't lower the pull enough to get misfires. I bought a used SW Model 19 that had that problem. Wouldn't fire about every 4 to 5 rounds. Had to have the springs redone.

My 686 is just under 9lbs on the stock springs and feels like greased glass.

Real sweet wheel gun. I've messaged a M64 to about the same trigger pull on the stock springs before too.

Obtaining a lighter DA pull has much more to do with carefully reducing friction between parts than lightening the springs.

Some good info that's already been offered is an action job by a competent 'smith. As noted, though, smooth is more important than light, and there are definitely limits to how low you can go, so be sure to test for reliability.

Someone mentioned getting more of your finger on the trigger - that can help, and radiusing of the trigger face and installing grips that reduce the distance to the trigger face can help in that regard. I find the SP101's trigger face to be particularly sharp, so any SP101 I'd buy would get a radiusing whether or not it got additional tuning.

The trigger mechanism of a revolver is largely about levers and leverage. Generally, smaller revolvers have smaller levers and therefore less mechanical leverage, so their trigger pulls generally tend to be heavier. As such, a bigger frame (S&W K/L), while not as light and compact to carry, often have a wee lighter pull weights, and can be tuned more aggressively as well (and hold an additional round). A good gunsmith can likely get a S&W K/L-frame down to 8.5-9lbs and reliable with factory ammo.

Finally, if you're only shooting DA, consider bobbing the hammer and converting to DAO as part of a good action job. All else equal, bobbing the hammer actually enhances reliability, so you can tune the revolver's trigger a bit lighter before you get into reliability issues.

The New Colt Cobra has an excellent light pull right from the factory. Others can be improved with very careful polishing of internals and regulating spring tension

Kimber K6S x 2

A S&W J frame with a Apex Tactical Duty/Carry spring kit will have a DA trigger pull of 9lbs or just under.

The felt different over stock is amazing.

I would say that the lightest is likely a S&W with a spring kit. My j frame is smooth but heavy. My K frame is much lighter. They made a bunch of K frame snubs over the years.

And there’s the excuse to get another revolver.

I agree with what others have said. I have six or so snubbies and have owned various others. For easy carry and a light DA trigger, my LCR is my favorite. For light DA trigger, my old-fashioned S&W Model Ten 2" is probably just as good.

Another vote for the new colts. I have both the new cobra of 2017 and this years night cobra. The triggers on both beat the pulls on several of my smith pc guns.

I bought a Ruger LCR because of its light trigger pull. If I could afford one, I would buy the Kimber. That has a phenomenally light and smooth DA trigger. I go to my LGS every couple of months just to try the feel and check if prices have dropped.

My LCR 357 has around 1,000 rounds thru it and the pull is pretty light. Gets smoother the more I shoot it.

I changed the hammer spring on my SP101 DAO to a 10# with a 8# trigger spring. Cleaned out the trigger spring chamber by finger turning a 1/4" drill bit thru it to clean up any left over machining debris....and installed hammer shims. The end result is a glass smooth pull that is way better than the factory original. I have half again as many rounds thru the SP101.

Even though the pull is slightly longer than the LCR...I find I can stage the trigger more readily on the SP101.

I have the .38 SP 101 and Colt Cobra (and a couple of .38 Smith snubs as well). The Cobra has, by far, the best out of the box DA trigger pull of the bunch. It feels, literally, to be about half the weight of the SP101... with none of the stacking at the end. I haven’t officially measured the pull weight, these are merely side by side comparisons/observations I have made myself.

I haven’t personally handled the LCR enough to compare, but I have heard these guns do have a “good to great” DA trigger pull out of the box as well.

Good luck with your search!

This one is 6lb 6oz double action and 1lb 8oz single action. My SP 101 is 8lbs 10 oz double and 2 lbs 7 oz single
My 36 is 10 lbs double and 3 lbs 7 oz single.

Colt Python.

Factory new, I'd say Ruger LCR or Kimber K6S based on my fondling. The new Colt Cobra is pretty good too.
