Back to Ryan's Video and his method of assembly. The disassembly levers on all my guns, that have them, are very tight. I would never have thought to do it the way he did. For those who didn't watch the video. The OFFICIAL, APPROVED method to reassemble a P320 is to slide the slide onto the frame and lock it back with the Slide Lock Lever. THEN and only then do you rotate the Takedown Lever. Ryan was skipping the step where you lock the slide back first. He were pushing the slide to the rear and flipping the Takedown Lever without locking the slide to the rear. There's a problem with this design, but this isn't the same as un-commanded discharges. His guns releases the striker after a reset, with the TRIGGER FULLY to the REAR, by wiggling the slide. More akin to a double.
My two P320s (a Carry and an X5 version) won't fire at all if you do this. The trigger won't go fully to the rear at all. You can clear it by just LOCKING the slide back, no need for full re-disassembly.
