Notably, the FBI found it was entirely possible to disable the striker block without the trigger being pulled. A combination of wear, inadequate design, and loose manufacturing tolerances.
They couldn’t get it to fire uncommanded however, unless they bypassed the trigger.
However, they got the gun because it had gone off uncommanded in the holster - with witnesses - and no hands or anything else near it.

To disable the striker block, they removed the rear plate, applied pressure to lift the slide up and away from the grip, then stuck a punch into the back of the gun to manually release the sear. Maybe this is the beginning of discovering an issue with the striker block, but this isn't simulating a failure that could happen under normal circumstances (specifically jamming a punch in the back and releasing the sear).
Not really, it doesn't have a firing pin block like every other striker fired handgun, it has a weird sear block thing from a hammer fired handgun because it's a shitty hack job conversion from the P250
The P320 does have a firing pin block. There is a lever that physically blocks the striker from moving. When you pull the trigger, the trigger bar lifts the lever, allowing the striker to move if the sear is also disengaged.
None of this is a sear block, or has anything to do directly with the sear. It will prevent the gun from firing if the sear were to fail.
