Has anyone ever had light strikes with a Polymer80 based pistol?

I see by way of youtube that some people have had some light [primer] strikes with their newly built PF940C "Spectre" based pistols.

I had it happen with an Advantage Arms .22 conversion kit installed on a Spectre frame (due to an incorrectly seated recoil spring/guide rod assembly),
but it never happened with a G17 upper.

I'm wondering, has anyone here experienced this?

Are you using factory weight trigger spring and striker spring? Is the trigger spring seated properly on the trigger bar?

The only time that I personally have had a light primer strike was with an Advantage Arms .22 conversion kit installed on a Polymer80 PF940 frame.

The frame had all standard Glock factory parts, and the trigger spring was properly seated.

The reason for the light strike in my case, as I discovered later, was because the recoil spring was not properly seated, and there was not enough spring tension to force it into battery.

But my concern regards light strikes with a 9mm upper, not a .22 upper, which I have not personally experienced but others apparently have, thus my question:

Has anyone here ever experienced light primer strikes with a P80 frame hosting a 9mm upper?

The primary cause of light strikes in Glocks is using too weak of a striker spring for the weight of the striker.
Stock spring rate is 5lbs.
Dropping below 4lbs definitely can cause light strikes if you have a stock weight striker.
If you have a lightened striker, the gun will usually tolerate lighter rate springs.
In the glock design, the trigger spring fights against the striker spring.
The easiest way to lighten the pull weight of the trigger is to install a HEAVIER trigger spring.
This seems backwards to people that don't understand that the trigger spring is actually ASSISTING in the trigger pull, not RESISTING the trigger pull.
It is the striker spring which is resisting the trigger pull.
