    Interesting. From the article it sounds like the magnetic field effectively made the weapon non-drop safe (by pulling the firing pin block clear) and the impact with the MRI machine sent the firing pin forward into the primer.

    We all hate 'disarmed victim zones' on principle, but an MRI machine is definitely place where a gun free zone is legitimately needed.

    I linked to this this story yesterday in another post:

    It is a very interesting story, I'm glad someone posted it by itself. The other thread was dealing with pros & cons of leaving your weapon at home when visiting the doctor.

    The magnetic energy of an MRI is amazing. Even a small metal object can become a dangerous missile in an MRI room.

    This isn't news to radiologists or LE. There are more than a few reports of officers being stuck by their duty belts to the sides of MRIs, of pistols being "jerked" from hands, etc., etc.. I know these have been published in LE publications. I don't work closely enough with Radiology to look over their periodicals, but one would think...... No surprise the empty was still in the chamber- everything steel was effectively JB welded!

    Failure To Follow Directions?

    Although the firing of the weapon certainly was very rare, the effects of such a powerful magnent should not surprise anyone. If one thinks about the movement of the 'metal' firing pin by an enormous magnent...is that rare (almost impossible?), yes...unlikely, yes...but understandable...certainly!

    It was stated in the article, that the tech...did advise the officer, and planned to secure the weapon before the process began...the cop misunderstood, and the tech was a little behind on his plan.

    Luckily on one was injured, and now everyone is a little 'brighter'...I'll bet some procedures are changed now...

    Well my Mom just had a MRI yesterday, they have locked lockers for people to store their stuff in, so you could ask if they have them before you go and store your gun there.

    Situational Awareness doesn't just mean Bad Guys.

    A quick review of why you shouldn't Cary a gun around a 1.5 Tesla magnet:

    The magnet pulled the firing pin forward causing the primer to be hit and bang! Even cocked and locked does not mean the firing pin can't move independantly which it had to. I don't believe any ferous metal is used in the primer cap at all.

    It would be interesting to see the case to see if there is a primer strike.

    The tech did a big oops! The gun was pointed in a safe direction though!
