It's the ammo right?

I have a wolf extra power hammer spring in my AR and only shoot milsurp. Is there an option for a g19 to run a heavier spring for the striker? Idk how striker fires work compared to hammer fired guns.

Yep, you can get stiffer striker springs from Wolff: Springs for GLOCK ® Semi-Auto Pistols

Although I'm not 100% sure, as I have not used an extra power striker spring, it will likely increase the weight of the trigger pull a bit. Probably not by much, since it's just an extra half pound over stock.

Is the striker channel free or gunk/oil/brass shavings/debris? (Assuming the striker rides in a sleeve or channel in a Glock)

It is a Glock. Does any of that matter?

Looks like light strikes. Something could be slowing the striker down.

Glocks can collect a ton of stuff and brass particles in the striker channel.

Yes, it is the ammo. BUT, you can probably improve your percentage by cleaning the firing pin channel. 800 rds would be enough to gum up the channel.

This issue (dirty FP channel) is common. This is an overlooked area in many guns. We mandate all duty guns be detail stripped, cleaned and inspected by an armorer on an annual basis. I get an unbelievable amount of gunk and brass shavings out of nearly every gun

Ive had enough problems with missfires, Feeds and jamming on Wolf ammo in my 1911's that I will not run it through my pistols. But Wolf has been great with my SKS' and AK's for many many years with no real issues. It's almost always on hand can be gotten in bulk and it's cheap.
