I stressed over this and finally gave in and got a P365, which I tore down and measured various things to assure it wasn’t as naughty as a P320. I wouldn’t even carry (EDC) a nice Glock which some PD reverted to, because of the unfortunate possibility of inadvertent discharge when re-holstering. For the P320 there was no real visibility of the risk from a slight trigger movement - for the Glock you know anything that moves the trigger safety opens the envelope.

Where do you go to read up on this?

Product reviews, trigger specifications, and such. It really is just a matter of personal preference. Firearms like Glocks don't have "active safeties" where you enable/disable them with a lever, but they do have a variety of "inactive safeties" which prevent the firearm from discharging when dropped/rattled/whatever.

gosh, there’s always some argument about the defn of “safety” when discussing Glock. A Glock trigger has a little spring-loaded tab which is depressed when you hold your finger on the trigger. When it is visible the Glock can not fire. This they call a “safety”, seems a little sketch but ok, I get the point. There’s some other internal features backing it up, but the trigger is most obvious.

The P320 had an internal lock-out widget that would disengage when you pull the trigger a wee bit and a spring loaded sear (? do they call it that for strikers?) one trivial whack away from releasing even if the trigger was not pulled to the break (the expected release point). I would call that absurdly wrong. The upgrade fixed this similarly to the P365.

The P365 has a similar lock-out widget to the P320 (they call it an internal safety in the manual), but it doesn’t disengage until the trigger is pulled into the break. The “striker” has a tab on it which is blocked to that point by the widget. You can disassemble it all and measure the distances the parts move to release, but I actually looked at a SolidWorks 3d model someone in the aftermarket industry shared with me and verified my pistol had the same dimensions at a critical point. I think if the striker tab or the widget broke it could fail silently. I check it about weekly or less.
