Revolver Double Action Trigger Pull

[boom boom]

All of my DA trigger pulls are smooth on my revolvers and given neuropathy that I have, I prefer to leave them at original weights and not monkey with them. The ones that need some help, I generally polish. But then again, I buy most of my firearms used and simply avoid those with bad trigger pulls with one exception where I had to fix a botched trigger job.

Instead, I work on hand exercises to keep my hands and fingers strong and buy firearms/grips that fit my hand to the power crease. I don't use the pad of the finger on revolvers and rarely on semi-autos.

Have a couple that are smooth enough to trigger cock (including a J Frame) which I would rather do then get into the habit of single action shooting which is why I do not have a single action revolver.

I'm pretty darned sure that your 17 has had work done to it. If the owner was really into target/comp shooting he/she may even have gone with a specific ammunition.
I have a m.15 Smith that was tuned to the extreme. About 7# da, but not reliable. Being strictly a range gun , I "cheated". Instead of swapping out the main spring altogether I employed the old trick of placing a spent primer cup over the end of the strain screw as a shim. That brought the strike just up to the point of consistent ignition , the increase in trigger wt. being only a few ounces. Certainly not an exact science - every primer cup dimple being different - bit it worked.

I shot both the 17 and 48 again today.
The 17 was flawless with 50 rounds each of CCI Blazer and Aguila Super Extra. I fired the last 50 of the Mini Mags from the other day and had 49 of 50 fire, one FTF that fired when rotated and struck again. I think it was that batch that was wonky.

The 48? Total flop. Only fired in SA mode, 2 of 6 fired in DA.

I broke it completely down and gave it a good cleaning. I found a bit of crud under the ejector star and in the channel that runs through the cylinder.
I also used Waveskis trick and took apart an old LP primer and installed it under the hammer spring screw. This did increase the pull weight and hopefully will increase the hammer fall energy.
I won’t be able to shoot again for a couple of weeks, so I’ll report back of this improved the reliability or if it needs a trip back to S&W <sigh>. .

Thanks for the suggestion Waveski .

Stay safe.

I've never had a bad batch of any CCI .22 , but it sure sounds like you got stuck with one.
It would be interesting to see clear images of the primer/rim strikes from that 48.

Observations like this make me wonder if our ancestors did much double action shooting other than in close range self defense.

That reminds me, in his book "No Second Place Winner," Bill Jordan talks about 15-20 lb double action triggers as if they were the normal thing.

While I may be wrong, I think having a trigger smoothed can also cause a reduction in pull weight due to less friction.

Not on the scale, but it really feels that way. So much so that I bought a second scale to verify.
