M&P9 Smith& Wesson Safety

[prc56]

My son just bought a m&p 9. I was looking at the gun and did not see a safety. I asked him about it he said it had a mag safety. Is this the only safety on the gun. And how does a mag safety work?

When there is no mag in the gun, it will not fire

The pistol has a mag safety (prevents the trigger from firing the gun if the magazine is removed), a firing pin safety (aka 'drop safety' - prevents the firing pin from hitting the primer unless the trigger is pulled to the rear) and a trigger safety (prevents the trigger from moving to the rear unless your finger is physically on the trigger).

That's a lot of safeties. The key is to never put your finger on the trigger until you're ready to fire.

You will also notice that the trigger is jointed. The gun will not fire unless the finger is pulling on the trigger on the lower piece of the trigger below the joint.

Yep, 3 internal safties, keep the finger OFF the trigger & the gun will not go BANG

Um that is absolutely NOT, repeat NOT a safety. It is a stupid annoyance at best and a dangerous "feature" that will get you killed at worst. I do not own an M&P so does anyone know how to disable this idiotic mag discon "safety?" It's easy to disable on the S&W .22s, the Hi Points, and the Bersas, but I don't know about the M&P mag disconnect.

So then what is it? I cannot, repeat cannot, release the striker when the mag is out.

Some people consider it an absolute necessity, like cops who might have unfriendly types try to wrestle them for their gun.

Some folks consider it a somewhat questionable hassle, like competition shooters operating under a cold range.

Fortunately the M&P series is available with or without. Your choice. Removing it is doable, but you need a spring and the ability to take things apart, put them back together, and to not lose small parts.

I have two M&Ps and neither has either a lock or the mag safety. My 45 has the manual thumb safety. I believe only the 45 comes with the thunmb safety, a nod to potential military buyers.

You can have the M&P your way assuming you live in a state that does not mandate mag safeties and whatnot.
