Default Magazine Safety or No Magazine Safety

So, now I own a full sized M&P 9 that has a mag safety and just purchased an M&P Shield that does not. I want to have both guns match, either with or without, I don't care which. Assuming it needs to be done by S&W or a gunsmith, have you any advice as to which is easier/cheaper? Remove it from the FS or add one to the Shield?

I should add that the shield manual of arms says they come both ways though I have yet to hear of one that has shipped with a mag safety.

I took my mag safety out in about 30 seconds and replaced the spring with one from a ball point pen.

Ok guys. I'm new to this. I come from Glock ownership, where everything is just one way period, no options. Let me know if I have this right. The M&P pistols come in:
  • Safe Action Trigger Only
  • Safe Action Trigger + Frame Safety.
  • Safe Action Trigger + Frame Safety + Mag Safety?
  • Safe Action Trigger + Mag safety

Then on top of all that, there's a model that simulates a DAO trigger pull?

Wow. I like choices.

Personally, I think less is more. My Ruger SR9c had a magazine safety and I removed it. It's a piece of metal, the shape of a U and extends through the slide. When a magazine is inserted, it pushed the safety up so the firing pin can clear it.

I don't know how they are on M&P pistols, but on the Ruger's, they just barely clear and it was visible on mine that is was dragging on the firing pin when fired. This can lead to light primer strikes. After removing mine in the SR9c I can see a visible difference in the impression of the firing pin on the primer.

Thanks for the info on the SR9 series pistols. I'm not a fan of magazine safeties. I tolerate them on .22lr pistols, no so much on major caliber pistols.

My LC9 is built the same way as the SR9c. I haven't had the firing pin out yet, but if or when I do, I'll remove the Mag safety in it as well.

I don't much bother with 22's either. Their just something cheap and fun to shoot for me.

I think I would remove the mag safety from the FS 9MM.
I have a full size .40 S&W with a mag safety.
I tried to remove it, and it looks like you need a different spring to make it work, so I put it back together.
Btw, it's a real pain to reassemble the mag safety.
The little spring & clip..... AARGH!
I don't rule out trying to buy the right style spring so I can remove the mag safety. It would be nice to have a gun without the ugly warning printed on the slide.
"Caution: Capable of firing with magazine removed". Blah, blah, blah. What an ugly thing to stamp into a gun.

I want a magazine disconnect. I donít know of anyone dying because they had a magazine disconnect, but I know of an Illinois State Trooper that is alive because he had one.

Thatís the good thing about the M&P line; they offer it both ways and you donít have to justify to anyone what you want.

Totally agree with your last line there.

But just to add to the first part...
2001 Manitoba RCMP Const. Dennis Strongquill was killed in the line of duty. The reason...as a left-handed shooter, he accidentally hit the mag release on his duty weapon while trapped in his cruiser, disabling it and rendering it useless.

Ultimately though I'd say the argument could be made either way.

Mag safety depends on the use of the gun. If you envision a situation where you are going to be in a fight / wrestling match with a bad guy, then as many LEO's will point out, being able to "safe" the gun by releasing the mag has some serious advantages.

If that is not the case, then you have a situation that could cause you to have one of two "also highly unlikely" situations:
1. You accidently drop the mag in a crises and are now holding a door stop.

2. You are in the middle of a reload when the need to shoot arises, and you are holding a door stop.

While all of these situations are unlikely, you decission should be based on which is the most likely to occour in your case.

.
In that situation, your support hand should be right at the gun with BOTH magazines. Insert one and solve the problem. Your weapon is not a door stop!

In addition, a partial/tactical/topping off reload is done from behind cover with no action in progress. Did your need to shoot beam in?

It's your choice, but the fear of magazine safeties is overblown. I'm sorry about the RCMP Constable, but left handed shooters trapped in the drivers seat are way behind the 8 ball regardless of weapon condition. He could have tapped the magazine (by hand or on an object) to restore function had he had time (and assuming the magazine didn't release after he was shot).

You are confusing and IDPA match, or a tactical simulation, with reality.

In the real world, most people in this situation will not have faced it before. The panic reaction resulting from the situation will prevent or slow down proper "situational awareness" for the average gun owner, no matter how much we think we are rambo.

For the period of time the mag is out, you ARE holding a doorstop with a mag-safe gun. Period.

Actually, I've been carrying firearms for a paycheck since 1969. Making it to senior citizen status has involved a firm grasp of reality and a heaping helping of dumb luck. Since we're speaking of reality, most all people fire 'till slide lock. In that condition, there is no difference between with/without the magazine safety.

I will conceed that if Howard Homeowner decides to do a top off reload, he will probably drop the partial mag and then go fishing for the replacment (although I doubt Howard has a spare in his jammies). Given his preoccupation with trying to get the weapon up (find the mag?), an aggessive intruder could be too close for it to make a difference if the weapon is a functional firearm or a impact weapon. On the other hand, Howard is also the person most likely to benefit from the inability to fire a round accidentally left in the chamber, so the sword cuts both ways. [Not to pick on Howard too much, it's occasionally entertaining watching some officers search for spare mags at M4 bolt lock on our stress course.]

Good idea for a question on a limted access site about any known tac reloads. A thread on the magazine safety produced something over 30 documented saves in a day or two. No injuries/deaths cited.

I will be telling my age, but when I started carrying my S&W Model 645 on duty I went to qualify at the Sheriff’s Office Range. The senior firearms instructor was inspecting my weapon before I attempted to qualify. Without asking he disassembled my 645, removed the magazine safety and handled it back to me. He looked at me and said, “You may only get one chance to get a round off at your attacker while reloading in a fire fight”. That was it. I still carry it today since I am an old head now. And he retired and they just recently named the new firearms complex after him. So I am guessing he knew what he was talking about back in the day.

I like magazine disconnects and feel those who are against them think they are some tactical operator because they subscribe to Guns and Ammo. PLENTY of cases of lives saved by the disconnect. And the left handed trooper? Sorry for that, but even IF he got that shot off, what are the odds he not only hit the guy, but scored a stopping shot? Cops have about a 20 hit ratio nationwide.

LOL, I subscribe to guns and ammo, it's always got good indepth reviews on guns. I don't think I'm a tactical operator, or even an operator for that matter. I also don't feel that if someone has a view different from mine, that they are wrong.
