Hey everyone,

Does any one have a link to a good instruction on how to remove the thumb safety on an MP?

Thanks!

Google M&P armor's manual. That's how I found out how to detail strip and reassemble the M&P. You can also see the Apex Youtube video. If you decide to sell the part after removal send me a PM.

Removing a manual safety on an M&P is not a liability concern, as the pistol is sold both ways from the factory. It takes about 5 minutes and is most easily done by removing the safety lever and switching the sear housing block assembly. Personally, I prefer having the ambi-safety.

Better safe than sorry.

I have heard this argument made over and over on the internet and in gun magazines, but in 16 years of police work, I have never heard it once in real life.

quite simple
Drive out the sear block pin
remove the sear block
take out the safety
replace the sear block
it is a 2 minute deal.

SOMEWHERE within just the last month or so, I read that S&W will sell you some "plugs" to fill the resulting holes left by the safety removal.

And that brings up a question. Are the safety vs. non-safety guns built differently, or do the factory issue non-safety guns simply have the "plugs" installed. I live in a handgun wasteland (Central IL - yeh, don't get me started about this shithole of a state:) - and don't have access to a non-safety model around here to look at.

Safe shooting!

I think the plugs for the frame are an urban myth, I removed the thumb saftey on mine and it is simple, but you are stuck with the notches in the frame. As far as the comment to buy one from S&W with out the saftey, I would have, but they don't offer the FDE frame with out the thumb saftey.

Looking at the two frames, with and without the thumb saftey, they just remove the material on the frame with the thumb saftey.

They are the same.
The factory non-safety pistols have frame plugs installed.
The little plugs just snap in place, they are quite ease to pop in and out.

Does anyone know where I could buy a sear housing and safety for my M&P45? Right now it has the plug and I'd like to trade up to the safety. I emailed S&W and they said that it would not be possible (despite the fact that the plug pops out).

Bullshit..I bought two of them for my midsize M&P from S&W about 2week ago, simply by calling and asking, when I removed my thumb safteys, They cost $3 apeice and you'll need 2. They do not interchange. Product code #'s are 392460000 frame plug (Left side of frame) and 392470000 frame plug (right side of frame) If you go to G&R website look up S&W pistols Grant has a good pic of a Midsize .45 without manual safteys...From the factory the frames are plugged.. To the OP call S&W's C.S. and use the product codes you should get the plugs, they are also very easy to install, and NO you don't glue them in place. The sear housing will hold them in place. Also, when you pull the sear housing out,and remove the saftey levers, on the left side of the housing there is also a spring loaded detent in the sear housing. The dentent clicks into the notches on the saftey levers, and basically holds them either up or down. This also should be removed, It'll come right out it's a small part so use some tweezers, hemostats, to grab ahold of it and lift it out of the housing. install the plugs install the sear housing and install the coil pin and you're in business.

i also like the Dark Earth full size M&P but do not want the thumb safety. Good to know you can get plugs...maybe I'll go out and get a Dark Earth today...

Since the factory sells the parts to make the change, since the factory certifies armorers and trains them to make the change, I am highly skeptical that it could ever be considered an "unauthorized" modification--numerous agencies here have pistols that have been so modified by their armorers and the sky has not fallen in.

It is still something I think is worth taking into consideration and i will definitely plug up the holes so that it is not obvious the thumb safety was removed by me.

SeaSoldier · #17 03-20-10, 14:11

I'm looking for a thumb safety if someone is selling. Just PM me a price.

Sounds like someone spent to much time with M.A.

I'm not a lawyer, but I don't understand how removing a safety or lightening a trigger could lead to criminal or civil liability.

If you intend to shoot an assailant, your decision to shoot is justified, and the bullets hit their intended target, what's the difference? If anything, you took away impediments to accuracy which might endanger innocent parties down range.

If you have an accidental discharge or shoot someone under ambiguous circumstances, I could however see a problem.

Does anyone have a discrete example of a LEO or legally armed civilian justifiably shooting an assailant and then being convicted of a crime because they removed a safety or their trigger was too light... so long as there was no unintentional discharge involved?

HK45 · #20 03-20-10, 20:12

I have no personal experience of such things but I have read a zillion articles by Ayoob and others that this can be used against you in court for using an unsafe weapon or a "hair trigger". I would also assume that a justified shooting ruling would be less likely under such circumstances.
