Light primer strikes when not fully releasing trigger.

[alpharius]

This is a hypothetical situation.

I am not involved.

Asking for a friend.

Suppose a person, let's call him Fred, is firing his home produced firearm of glock 19 pattern and gets frequent light primer strikes.

So Fred tries this other guy's, let's call him Bill, home produced firearm of glock 17 pattern and gets the same frequent light primer strikes. This uses different ammo than the 19.

Bill shoots his 17 and gets no light primer strikes.

Bill shoots Freds 19 and gets no light primer strikes.

Only difference between Bill and Fred is that Bill lets completely off the trigger between each shot and Fred only lets up to the reset.

Fred tries letting off the trigger completely between shots and has no malfunctions.

What could be the problem?

Should work if trigger reset. Many people ride the reset while shooting.
So, I’d say you have a gun problem if it doesn’t work unless you let finger off trigger.

Yes. Thats what I thought. Just trying to figure out what the problem could be. Any ideas? Stronger firing pin spring?

That's tough as I haven't heard of that particular problem, but the striker spring is the first thing I would look at as well as a thorough examination of the trigger pack parts.

Try a very firm grip. Riding the reset (for me) requires a looser grip to maintain dexterity of the booger hooker. Slide may not be seating fully.

If reloads, try seating the primers a bit more.
