The older lady still had a bobby pin in her hair when she went for her MRI. It ended up high in her nose requiring surgery to remove it. | |||

The first time I had an MRI the question was asked if I’d ever done any metal work involving a grinder for the same reason. Because I’d often used a Dremel, I thought it best to say I had, and they took an X-ray to check to see if I had any metal fragments in my eyes. Even though I’d always worn eye protection before, I’ve always had that in mind ever since. Long ago I heard a story about how an LEO took his pistol close to an MRI facility and when it was snatched into the machine it discharged. At the time that seemed unlikely, but later when I was thinking about how some guns don’t have firing pin blocks, I could see how it would be like dropping such a gun muzzle down, but with much more force. As for someone’s taking a gun into an MRI facility, I can also see how that might be more likely to occur in a place like Brazil. ► 6.4/93.6 “Wise men talk because they have something to say; fools, because they have to say something.” — Plato | |||

Well, there you have it. Even though the pistol is a Series 80 Colt which has a firing pin block, the strength of the magnetic field was such that the firing pin block was disengaged, and the pistol was drawn into the MRI tunnel and struck one of the sides of the tunnel, thus causing an inertial discharge. A non-80 Series Colt- or any 1911-pattern pistol and other pistols which lack a firing pin block- might discharge in the very same way if dropped (or struck) on a hard surface with sufficient force to drive the firing pin forward and detonate the primer of a cartridge in its chamber. This is not what people are claiming in their anecdotal re-tellings and their lawsuit(s) against SIG-Sauer. Those people are claiming that their P320- holstered or not- fired spontaneously without any human intervention, and I stand by my statement that this is simply not happening. In instances where the P320 is firing a cartridge in its chamber, the trigger of the pistol is being pulled or pressed. Also, I maintain my contention that a safety blade (or tab) on the face of the P320 trigger as is present in most other striker-fired pistols would have prevented a substantial portion of these discharges. From the link: At the time the weapon discharged, it was reportedly in a cocked and locked position; that is, the hammer was cocked and the thumb safety was engaged to prevent the hammer from striking the firing pin. A live round was in the chamber. (Many people who choose this weapon for personal protection will carry it in this manner because it allows them to quickly fire the weapon if needed.) When the firearm was removed from the magnet, the gun was still in a cocked and locked position. An empty cartridge was found in the chamber. The presence of an empty cartridge in the chamber is highly unusual. If the thumb safety were not engaged and the weapon fired normally by depressing the trigger, the normal backward recoil of the slide should have automatically ejected the empty cartridge, and a new live round should have automatically been chambered. As discussed earlier, the thumb safety performs two functions: it prevents the sear from releasing the hammer, thereby preventing the hammer from striking the firing pin; it also locks the slide in place, preventing retrograde motion of the slide and automatic ejection of the empty cartridge. Thus, the presence of an empty cartridge in the chamber confirms that the thumb safety was engaged at the time the gun was fired. Given that the thumb safety was engaged when the gun discharged, it is also likely that the normal trigger and hammer mechanism of firing the gun was bypassed because the thumb safety would have also prevented release of the hammer. The gun likely discharged as a result of the effect of the magnetic field on the firing pin block. The firing pin block was probably drawn into its uppermost position by force of the magnetic field. The firing pin block has to overcome only light pressure from a relatively small spring to release the firing pin. The pistol was likely drawn into the magnetic field so that the muzzle struck the magnet's bore first. With the firing pin allowed to move freely in its channel, the force of the impact on the muzzle end was sufficient to cause the firing pin to overcome its spring pressure and move forward to strike the primer of the chambered round. This account explains how the weapon discharged when the thumb safety was engaged. | |||

My plan at the moment is to not go near an MRI machine regardless of whether I am carrying or not.... In fact, now that I think about it.. since I spent 35 years cutting steel damper plates out of fireplaces with a sawzall and grinder with very little osha approved protection... I probably better pass always.... My Native American Name: "Runs with Scissors" | |||

I you are afraid it will “fire on its own” sell the FCU you have and replace it with a FCU with the manual safety. A few simple uts with a DREMEL and you are GTG. Nice is overrated "It's every freedom-loving individual's duty to lie to the government." Airsoftguy, June 29, 2018 | |||

Your 320 is fine. JFC. | |||

Wasn't one of the prior issues was the trigger weight was too high causing more inertia when dropped which could contribute to firing? I think there were other similar improvements too that would yield better safety. | |||

I am not interested in owning a 320 at this time. If I want another striker fire it will be a G17 or G45. Then again, I won’t CCW a 70’s series 1911’s these days either (as a range only pistol it is a different story). Many here would do either of the aforementioned without worry. Perhaps I am paranoid. I have to be comfortable with the firearm in question and if I am not due to perceived mechanical shortcomings, I will avoid that particular type or model. Everyone’s comfort level varies. | |||

I agree that everyone’s comfort level varies. Not quite applicable to this question though. Are 320’s safe? The answer is absolutely yes. Is a series 70 safe? Well, it isn’t drop safe. Comfort level aside, the safety question is pretty black and white. The 320 is drop safe, it won’t just go off, and there has never been one shown to just shoot people in the melon without provocation. So yes it’s safe. Would you carry it? Totally up to you. Comfort level. | |||

I can categorically state that all prior and current owners of 320's will die, if they haven't done so already.  | |||

Here's a reason why this question continues to pop up. One of the top news stories listed under the Google search bar. MPD is switching to Glock after a few mishaps. https://www.wisn.com/amp/artic...ly-complete/43661021 | |||
