P365 Safety Function Question

[1075tech]

Recently acquired 2 P365s.

First is a standard 3.1", manual safety version. Swapped the FCU into an X size grip module for mag compatibility with the 2nd one. Standard trigger with Mcarbo springs installed.

2nd one is a 365XL. 3.6", manual safety. Factory flat trigger. Factory springs.

I bought both of these used.

Doing some dry fire exercises I noticed that the standard version, the safety will not go on if it's not cocked. Also, with the safety on, I cannot rack the slide. This is the same in either grip module.

The XL, the safety can be placed in the on position regardless if it's cocked or not. With the safety on, I can still rack the slide.

Both safeties work in that they will not fire in the on position.

I don't see any reason they should function differently. Any thoughts?

That's interesting. I found this on another forum

Maybe @divisionarmsllc can chime in I think he is a SIG Armorer.

I just messed with mine.

Striker not cocked, safety engaged = slide locked
From slide lock, engage safety = slide unlocked

Take the slide off the frame. You'll notice that the takedown lever is locked down and the safety will not move. Hit the slide release and you now will be able to manipulate the safety. You can use the takedown lever and slide lock to "reset" the FCU and engage the safety, pull the trigger, etc. You can see how the safety blocks the sear from releasing.

Now look at the slide.... you disengage the striker from the drop safety, which let's it travel forward to an "unlocked" position.

Put it back together, pull and hold the trigger, try to cycle the slide, you can neither engage safety or work the slide.

Working hypothesis: unlocked striker and engaged safety creating a mechanical lock that doesn't allow the slide to travel rearward.... uncocked and locked if you will.Without the rearward travel of the slide to reset the striker the FCU doesn't reset.


Why it's that way I can't answer or it would be different
