Help an ignorant person - how can I pistol discharge with a finger on the trigger? MP40 in particular.

ANY mechanical devise can fail. All weapons should be considered loaded, and a constant effort to be treated as such should be mindset.

That being said, some models have better track records than others. All my handguns have hammers with built in guards to reduce the likelihood of an ND by dropping one.
But there is never a complete guarantee. Guns are dangerous if safety precautions are not adhered to, and life can be dangerous in and of itself.
You can reduce risk, but you can never remove risk all together.

The main issue is that the firearm isn't drop safe. Yes, you should treat every firearm as if it were loaded, but it's not unreasonable to expect a gun to only fire if the trigger is pulled.

Nobody wants to point out that mossbergs are not drop safe?

I recall the OP posted a thread where he had an ND quite some time ago.

Professional instruction should have followed that incident as immediately as possible.

on the list

It needs to be at the top of that list.

Ignorance is not necessarily a sin. But remaining ignorant while continuing to handle firearms semi-regularly is.

You also claim to be paranoid regarding gun safety due to the aforementioned ND. That comes from a lack of confidence. Which stems from a lack of competence. Both can be fixed with well-qualified training.

I'm clumsy. Every gun I've ever carried for a significant length of time in my life I have dropped. My most used carry guns have been dropped many times, almost always over concrete or asphalt.
Nothing's ever gone BAnG!

Have a good lawyer ready.

Or write a booklet.

M&P pistols do not have palm safeties, or grip safeties, etc. The hinged trigger has a step/nub/ledge that prevents the trigger being activated by inertia, unless the hinge has been expanded, moving the step/nub/ledge out of position, by something like a finger being upon it. There is also a firing pin block, which is a separate drop safety.

Let me re-focus the conversation on to my .40 S&W. Obviously, no matter how hard anyone tries there is no way it's going to go bang if there is no round in the chamber. Let's move past that. This pistol is a Springfield XD with a grip and trigger safety.

My original question involved how the grip and trigger safety worked in conjunction. If you don't know the pistol, that's fine. I'll poke around a more specific site to understand how this specific safety system works. It's more of an "engineer wants to know" question.

Meanwhile, since the Sig 320 is having it's issues, it appears that the Barret sniper rifle is having issues as well.... but let's not go there.

Springfield XD safety system explained.

I got a 320 years ago, sig sent me a notice and asked if I wanted it to be repaired under it’s Voluntary Warranty.
I wonder what went on after that

OP orginally called his gun "S&W M&P chambered in .40". The EZ series with the grip safety doesn't come in caliber .40 S&W.
