I'm flabbergasted unless I'm missing something. Decided to swap my flat trigger to a standard on my P365x. Have done it a couple times, so not unfamiliar with the process. Whenever it's back together, the trigger does not drop the striker. There is tension on the trigger, but it doesn't trigger anything. I've put it back together several times last night and today. Even swapped it back to flat trigger and XL frame with it still occurring. It is NOT the trigger return spring and turning it upside down doesn't trip the striker. Did nothing to the slide group, so I doubt it is an issue with the upper.
This is a manual safety model, and even assembling the P365 with or without the safety doesn't drop the striker. Been watching SigGuy's P365 disassembly videos and can't track down anything wrong.
