In newer P365 series pistols, the striker return spring that pulls the firing pin back out of the breech after firing has been omitted. This alters the manual trigger safety for better or worse.
In the original P365 series design you could NOT engage the manual trigger safety until AFTER the striker was cocked.
With the striker return spring omitted, you can engage the manual trigger safety anytime that the firing pin is inside the breech, but NOT be able to engage the manual trigger safety if the firing pin has retracted from the breech but not cocked.
Example, if you have dry fired the P365 and the muzzle is pointed downward so that gravity is keeping the firing pin inside the breech, you can engage the manual trigger safety. However, if you dry fire and the pistol is tilted backwards so that gravity pulls the firing pin out of the breech, you cannot engage the manual trigger safety until AFTER the striker is cocked.
I have not determined whether or not this will cause any functional problems during actual use, but it is very disconcerting to have a variable operating condition of the manual trigger safety.
One issue that the omission of the striker return spring causes is when you have removed the slide and depress the striker safety downward to check it's operation to make sure that it moving freely, the striker can move forward and lock the striker safety downward. You then need to push the striker backward. It doesn't cause any operational problems that I am aware of, but it is annoying.
FYI, my P365 which I purchased in 2020 has the striker return spring installed in the striker assembly. It has never had an issue with light primer strikes, or any malfunction whatsoever.
