M&P 9 fired while inserting magazine

[CamG7488]

Unfortunate situation while at work, I was inserting a fresh mag into my pistol when it fired and struck me in the leg. I inherited this gun from my grandfather who had a gunsmith replace the trigger to a APEX trigger. We’ve had several visits at the range no problems.
This shouldn’t have happened. Our office was full of people standing around and there really wasn’t a safe direction to point it other than towards myself.
What the ****! Would cause this to happen?
I was aware that there was a round in the chamber, but have inserted mags hundreds of times this way with no bad results like this.

That's terrible news. Hope the wound isn't too serious.

Is it a 1.0 or 2.0?

Respectfully, loading that magazine into your pistol, with an already chambered round or not, or otherwise manipulating it at work in a public area crowded with people, was an irresponsible act and perhaps even criminal in the event of a discharge.

Pointing it towards yourself is not a safe direction.

Hopefully this event can be filed under "things that never happened."

A firearm is always pointing at something. Always. There must be a federal law requiring all M&P triggers be replaced with Apex triggers.

No mystery.
The trigger was pulled or pushed during your "administrative" magazine maneuver.

The M&P9 trigger bar movement is required to depress the independent spring-loaded striker blocking plunger and simultaneously release the trigger bar-sear engagement, which then allows the cocked striker to ignite the primer. BANG.

The event had nothing to do with an Apex trigger installation.

You defeated the three M&P9 safety mechanisms.
1. Articulated trigger passively prevents its movement unless the center tab is depressed, same with Apex.
2.With the trigger at rest, the trigger bar tab resides off of the safety plunger. The trigger bar had to move rearward for its tab to depress the plunger and unblock the spring-loaded striker.
3. The rear of the trigger bar rotates the rear of the sear downward from its engagement with the striker tab allowing its spring to power the tip of the striker into the primer.
#2 & #3 are geometrically timed to function simultaneously by their arrangement on the trigger bar.

The primary safety on any firearm is muzzle direction. This rule was violated.

Why were you messing with the gun it the office? Why couldn't you point the gun at the floor?

Sound like you pulled the trigger.

Do these kind of posts happen often here ?

More holes in this story than the reported one in OP’s leg…

Well, at least the OP had the option of telling us about the accident to keep at least me on my toes. If I DID have reason to mess with my gun in a roomful of humans, at least point the gun at whoever is the first person around you that you hate the most! Them bullets hurt; shoot someone else, not your leg. That must’ve hurt. I’m glad you’re okay.

More than there should be.

I agree with this post. I have 3 S&W—M&P—9mm and have never had anything like this happen. Two of my M&P’s have Apex triggers. The factory trigger as well as the Apex trigger have to be pulled and the trigger safety defeated for the gun to fire.

Missing were the portions of the story regarding OP being fired from that workplace and arrested.

The type of work I do, it’s dangerous.. I was getting ready to leave out in the field and the safest place to point was towards my led so it wasn’t anybody else’s.
Police report stated malfunction, as I had six witnesses and standing around me.

Nope. Actually still employed. And was investigated as a malfunction.

You other I would’ve probably been fired.

You on the other I would’ve probably been fired. That’s what happens when you put in 16 years at the same company. Loyalty.

Absolutely dumb on my behalf.. I would agree but it was the safest direction at the time.

I wouldn’t and didn’t pull the trigger.. idk man.. 6 people were questioned by police.. they said the exact same thing. No trigger was ever pulled..

6 people in your office told the police that they just happened to be staring attentively at your forefinger while you were inserting a magazine into an already loaded pistol and can, therefore, attest to the trigger remaining unmanipulated by you.

You said you manipulated a pistol you knew to be loaded, in a crowded office, while pointing it in the safe direction of your own body, but you wouldn't pull the trigger.


Okay.
