Just remember it was ~50 broken strikers out of 300,000 sold - all but 2 of those from guns made prior to June 2018. And the 2 post June 2018 breakages were noticed within 500 rounds (and they broke in weird places like the sear or the middle of the shaft -- not the tip like the March-April 2018 breaks).
VAspence put his through the 2,000 round challenge with no issues:

Mine had 4 failure to extract stoppages (at rounds ~1300, 1600, 1750, & 1900) using all $0.14/rd federal aluminum cased ammo, but I bet it would pass with cleaner burning brass cased ammo. My slide ended up being replaced (for free under warranty) due to breech face pitting around the primer pockets, which may well have been caused by that aluminum ammo.
Relatively few people have the lightning strike striker - maybe a couple hundred - with at least 1 person having light primer strikes with it. I know LSI made their own revision after a few months, so maybe there were more issues?
I know there were a couple guys who had early model strikers break after 1,000 rounds, but I know of none after 2,000. My May 2018 striker is approaching 10,000 rounds and I know another guy who is at 15,000.
Aside from a few dim night sights or blemished finishes, the only real issues people are occasionally reporting with 2019 P365s are feed/battery issues especially with some 147 grain ammo. The number of complaints are small compared to units sold, but there are still some guns that need to be sent back to NH to function correctly.
