A 1911 should not fire unless the thumb safety is off and the grip safety depressed prior to squeezing the trigger. Unless the MRI unit released these safeties, or the gun was in an unsafe condition; either worn parts or kept unlocked with the hammer down on a chambered round, or a combination of both, I don’t see how this could happen.

I think that inertia could move the firing pin forward with enough force if the gun impacted muzzle first. Anyone else want to weigh in on this? I know I’m going to check out my
1911 when I get home and see if this is possible. (No, I’m not going to throw it against the wall to find out!)

Yeah, I read the complete story AFTER I posted (a bad habit). It seems the magnetic field disengaged the firing pin block and allowed the firing pin to strike the primer discharging the weapon.

Inertia will indeed cause discharges in a fall.

The original design of the 1911 has a pin susceptible to it, but some designs today do not. The force needed to actually do that will vary based on the weight of the pin and the forces of any (if present) springs it has to overcome to do so.

If you read the article it explains that the inertial firing pin block was moved out of position by the magnetic field and the impact of the pistol hitting the magnet caused the he firing pin to hit the primer. Firing during drop tests with the muzzle down was why they started using the inertial pin block in the series 80 colt 1911s.
