Install magazine disconnect safety?

[RoosterDude11]

Please go easy on me. I know some people will say "why would you want to add a mag disconnect?". Well, I have a couple of reasons and won't bore you with that now.

Is it possible to install the mag disconnect safety mechanism to an M&P pistol that never had one? If so, can those mechanisms be purchased from S&W? Thanks!

What model are you putting it on? I took one off my MP 9c the whole sear housing
Having said that I think it is one of the most UNSAFE things you could ever have on a carry weapon.

As a peace officer it is one of the most valuable features to have on my pistol. If a bad guy gets my gun, all I have to do it press the magazine release button. It can save a lot of lives. I have it on my duty pistol, and my carry pistol.

Yes I stand corrected...for LEO it's very important...for civilians the worst invention ever
I wasn't thinking of that context. When I had my FFL/SOT and trained officers it was an important addition. When we trained civilians it was a disaster

I don't understand what this does.

Also, if a bad guy gets a hold of your gun, how do you ouch the mag releas?

Not trying to be a smarty ***, I really just do not understand.

The magazine disconnect prevents the gun from firing when the magazine is not inserted. In LEO there can be a struggle for the pistol, if the officer can hit the mag release and drop the mag the pistol cannot be fired by the offending person. This occurs when the "bad" guy is trying to get the officer's gun during an altercation

That just doesn't make much sense. To many variables and adrenaline to even think " it's time to press the mag release" while fighting for your life. In a CQ situation you would be better served using empty hand and/or knife tactics. With the current technology of retention holsters if he has your gun your probably not in good shape enough to hit the mag release. It's all debatable and my 2 cents.

"(Note: 1980-2014) In the last 10 years the average number of officers killed with their own gun was . . .

2.2 per year. According to the FBI UCR numbers, the average of all officers feloniously killed  is 50. Gun grabs account for 4.4 percent of officers feloniously killed in the last 10 years with their own weapons. The number of sworn police officers in the United States in that period has averaged about 523 thousand a year. So the rate of police open carriers who are killed with their own guns is about .42 per 100,000. It’s not zero, but it is low.”

There are ton of reasons NOT to have a magazine disconnect for civilians. I can't think of one reason why to have one for non LEO. You could say for the children but no one should ever be leaving out a pistol that children can reach to begin with.

With current stats I don't see it serving LEO very much either. At the current rate it's not going to save "lots of lives" either.

I personally know an officer who got in a struggle, bad guy got his steel frame S&W 45. Couldn't get it to fire, safety was on. Officer then had time to get back in the fight for the gun and dumped the mag.

Magazine disconnect is not for me ...

If there is a bullet chambered and a struggle ensues over possession of the weapon I'd prefer to send that round into the attacker using my trigger finger rather than trying to deactivate the firearm by dropping the mag with a movement of my gripping thumb to the mag release button.

Just trying to release the magazine involves loosening my grip on it to press my thumb on the magazine release button. The gun may be wrenched from my hand before I manipulate the mag release, giving the assailant possession of a loaded weapon.

Not having a magazine disconnect allows a reload to a full magazine if cover and opportunity presents itself, while still being able to fire a chambered round if needed.

I'm not going to let anyone get close enough to grab my weapon from my hands without putting a few rounds into them before they get that close.

Just my thoughts on this, YMMV

My preference would be not to have a mag disconnect from the perspective of a tactical top off (assuming you know how many rounds you fired, & have cover).

More focus on gun retention techniques, tactical blade, etc. An argument could be made either way. Tough call!

Similar to having external safety or not. See Glock!

So it was the safety that saved him and not the mag disconnect. OK, I could see that as it requires no action on the officers part in disabling the gun.

This is for an M&P 2.0 9mm and M&P 9mm Shield.

My agency carried S&W pistols with the magazine disconnect for years. If any pressure is applied to the trigger as the magazine release is pressed the disconnect will not work and the pistol will still fire.

We also had the issue of a few service pistols that would not fire when the disconnect malfunctioned. Fortunately, that occurred on the range during training.

To respond to the OP's question, the best way to acquire a magazine disconnect for a defensive pistol is to purchase a pistol that was originally designed and manufactured that way. That would ensure a greater likelihood that the disconnect and pistol will function correctly and would be the most cost effective.

That may not be the answer the OP was hoping to read, but when a person is looking for specific features on a defensive pistol, such as safety devices, the safest bet is to purchase a firearm that has those features as OEM.

Thanks. That was kinda what I was thinking. If I wanted that feature, I should have bought the pistol with it. Thanks to everyone for their comments.

This thread is ridiculous, if he wants one he wants one. Nothing more needs to be said. All you have to do is get a sear housing with a mag disconnect safety and install it in your gun. It's a very easy process to make the swap and it will work just fine. Let me dig around in my armorers kit, I might have a housing with a mag disconnect in there as I have taken a few out of guns from people who did not want them and installed a few into guns for people who did.

ETA: I have one for a M&P 1.0. Cannot advise if it will work in a 2.0 or not.

 

[silversnake]

I agree if he wants one it's his choice.

I'm not a fan of mag safeties myself but Mas Ayoob and others have documented cases of officer's lives being saved by activating the release during a fight for the gun.

Safety kept him from getting shot after the bad guy almost knocked him out. Gave him time to re engage and while fighting over the gun dumped the mag so it couldn't fire.

Yes, exactly. If there had been no safety the mag disconnect wouldn't have mattered.

Approximately .42 per 100,000 LEO get murdered with their own gun. While it may be department policy, it's not a very good and/or well thought out one.
