My son owns a SIG P320 Compact 9mm w/the APEX flat trigger.
After reading some of these threads about the P320 going off when dropped, I decided to test it myself on his.

I loaded up a 15rd mag w/14rds of 124gr FMJ topped off w/a snap cap. Chambered a separate snap cap before seating the loaded mag.
As suggested, I held the P320 hanging by the trigger guard w/the rear of the slide a measured 4' off the carpeted floor.

It required 17 careful attempts to get 10 solid hits on the rear of the slide as seen in the various posted videos.
Trigger was checked and reset after every attempt.
End result: At no time did the trigger move enough to drop the striker, it still required a full pull of the trigger to do so.

This could be due to using a Compact, or the APEX flat trigger, both or ???

I do not claim this was scientific testing, but thought I would post the result for those who might be interested.

I dropped my stock subcompact about 4.5 feet from floor, 3 different times, it didn't fire.

Still not sure I trust it, but I will have to buy a new grip, it has a nice flat spot now on the back.
