Lyman - electronic trigger pull gauge

[AIRret]

We are looking for a trigger pull gauge.


The Lyman electronic trigger pull gauge has good reviews and seems easy to
use, but I trust the feedback on this forum more. So do you fine folks have any recommendations?



I'm not sure if I started this thread in the proper category.

[Bawanna]

It'll work here or maybe the tech section?

We have one here at the department and it's a good unit. Easy to use and consistent. I used it when I put the 5# striker spring in my PM45 both before and after installation. Worked good.

Like all things like this that generally don't get used much after the initial test every trigger you own I take the battery out when not in use. I think there's even a storage place for the battery in the kit.

Thanks, cyber Hubby.

My other Husband is starting to tinker with gun set up and the gauge would be helpful.

I believe it is one of the better trigger gauges out there at a reasonable price. On my list of wants. I have a manual, spring operated one, but the range is poor. For the little I use the thing, I forget to order a Lyman.

Thanks garb!
I appreciate the help and unless others on the forum have reliable experience
that would change my mind I can now make that choice confidently.

I put the Wolff spring kit including the striker spring in my PM40, I thought it increased the trigger pull but may be the same. Still feels like a normal DA revolver trigger. Would be interesting to test it.

r. Would be interesting to see what difference in pull there is.

[Bawanna]

That's the beauty of the gauge. I checked my PM45 with all stock stuff in it and then again with the 5# striker spring. It improved only a bit but got a little better with time. I haven't checked it in a long time.

I think my factory spring was on the low end of the scale so not a big difference, someone with a factory spring on the high end of the scale would notice more improvement.

It's still very good with either spring, so I call it success.

[Baklash]

I don't understand the need to replace the standard striker spring with a 5# spring when the pull is so nice already with my cw9. Of course, this is my first Kahr and I'm not that knowledgeable, but I thought the trigger pull was about 7# and the long pull was a safety thing. Wouldn't a 5# spring make it easier for an accidental discharge like the sheriff who got hung up on his drawstring? Just askin'. I'm sure someone will educate me here. ;)
But I can't imagine making my cw9 any better than it already is. I love it.:)

Hi backlash
The reason I had one was because I had bought a heavy duty recoil spring set and it included the striker spring. I put in one recoil spring at a time then after shooting it, I thought that why not try the try the striker spring. The striker spring doesn't make for a hair trigger. Still long and heavish.

[Bawanna]

True it's hardly noticeable. It lightens it a bit but the length of pull remains the same. A 5# trigger in a DA like pull isn't a bad thing at all.

That sheriff had a Glock with a very short Single Action type pull, different ball game.

My wife has a old 9mm glock. It shoots good but that last bit of trigger is very heavy. Way more than my newer 10 mm glock.

The Kahr is way smoother but quite a bit longer. What I don't like with the Kahr is that when i practice aimed fire it seems to take forever, just keep pulling.

[Bawanna]

Your wifes glock probably has a NY trigger or an 8# the parts are slipping me mind wise, connector?. They were designed so that you really have to want to pull that trigger before it will fire.

You can easily swap a few parts and hers will be the same as yours. That isn't always a good thing.

After my operation I would not want a glock in my purse.

To me, I guess it's more important how a trigger feels vs. the actual pull weight. However a gauge would be useful whenever you make changes (like springs) or start tinkering (like AIRret's real husband). It could also be helpful to measure an aging firearm to see when the springs may be wearing out and in need of replacement...before they possibly contribute to a failure.

Oh Bawanna, I think someone hacked your account and used it to spread misinformation about Glock. In no way does Glock have "a very short" trigger pull. And I know you know that, because you've owned Glocks.

For comparison, consider:
The Standard trigger on Kahr pistols has a 3/8" pull
The Enhanced trigger on Kahr pistols has a 1/4" pull
The Glock trigger has a 12.5mm (1/2") pull

Notice that the Glock trigger pull is twice as long as the Enhanced Kahr trigger and 33% longer than the Standard Kahr trigger. Characterizing a Glock trigger as "very short" is misleading.

It is generally agreed that Kahr pistols, most of which have no external safety mechanisms, are safe because of their long and heavy trigger pull. As shown above, the trigger pull on a Glock is significantly longer than on Kahr pistols. And although, in stock configuration, the weight of a Kahr trigger is slightly more than a Glock, there are many here who advocate changing striker springs in the Kahr--altering the trigger weight. Doing so may likely reduce the Kahr's trigger weight to match the Glock. So in the end, these owners are carrying a Kahr pistol with a trigger which is the same weight as a Glock's, but with a shorter travel. Yet, they still believe their gun is safer than a Glock.

I won't even address the Glock "Single Action" comment, except to say that on both Kahrs and Glocks, the striker is partially charged by the action of the slide but is fully cocked by pulling the trigger. That classifies both of these pistols as Double Action--and recognized as such by IDPA and others.

The only way to tell for sure if it's an improvement is to install a five pound return spring. IMO it doesn't make the gun one bit more dangerous and improves the trigger pull a lot. A good trigger is a prerequisite for accuracy. For the cost it's worth a try.

The majority of that long pull has zero resistance, the striker is far more charged on the Glock than it is in the Kahr as that is the resistance you feel the whole trigger pull.

So considering the actual make something happen trigger pull the glock trigger is pretty short, very similar to a 1911. You can easily make it short and hard or short and light but it's short.

Try pulling the Glock trigger half way and then changing your mind and letting it go. It ain't gonna happen.

I just measured my kahr pm40 and my wifes g19
The kahr from the resting point to where it breaks it is 5/8". The glock is a half inch.

[Bawanna]

I'm surprised it's that much on the glock. Are you including over travel or just to the break point which would be very difficult to measure.
I don't consider it trigger pull until the trigger is actually doing something. The Kahr trigger is working from start of pull.

The Glock has a little free play, then the resistance. It's not long. But it don't matter to me either way neither. They work, I know how it works and I remind my pointy finger all the time not to tickle that trigger till I'm ready for the boom.

[100percent]

I used the same criteria on both guns and measured from the resting point most forward on the trigger till the snap. The Kahr has about an 1/8" of free play and the G19 more than that, mostly because of the safety release in the center of the trigger.

I know that the trigger is not the same type of action and normally wouldn't think that a glock would fire if I just touched the trigger.

Kind of like comparing apples to bananas eh?

[Bawanna]

Or sheep to Zebra's depending on who your talking to.

I'll have to play with mine a little bit at home, boss frowns alot when I play with it here since it ain't suppose to be here. I guess 1/8" free play would almost go unnoticed on a Kahr.

I hate to show my ignorance here, but I would rather do that now and learn something than stay forever ignorant, so here goes.:o Is the return spring the same as the striker spring? And how does making it lighter actually improve the trigger pull? Is it that a lighter pull prevents movement of the hand off target? Many thanks in advance for some clarification for me. :)

[100percent]

The recoil spring pulls the action closed. the striker spring is mainly what you feel when you pull the trigger and pull the firing pin (aka striker) back. It is wrapped around the firing pin and holds it back. A stronger spring pushes the firing pin faster but makes more trigger pull.

I would guess that the return spring might be called recoil spring.

I waited till near dark today and shot a mag out of my Kahr, I didn't hear one gong. damn.

[Baklash]

Now that makes sense, the return spring and recoil spring being one and the same. Why didn't I think of that? Probably the same reason I didn't invent velcro or bobby pins.:( Just not smart enough.

One more plus for the Lyman electronic
