Get rid of the WD40 and get some real gun lube also look into Wollf extra power mag springs.

Rusty slide is an issue in humid climates - mine rusted when carried it in FL for just a couple of weeks (stainless steel not so stainless). A less volatile gun oil would probably be better.

Picked this up in November and just hit 2000 rounds. I like it a lot. I clean it every 1000 rounds and lube it before each session. No malfs yet.

I'd make sure your grip isn't what's causing your slide to not lock back before blaming the mag. Are you riding the slide stop with your thumb?

Idk got a gen 2 and 3 that have had 1 FTF total and it was pos silver bear ammo.......prob. 15k rounds.....and the op's m&p is at 2.5 failures per 500 so u are still doing better
 . Prob is either a wrist or spring issue though. I had problems with a G36 and a new recoil spring solved it but most of my friends and family have issues controlling it still.

I'm not exactly sure how many rounds I have through mine but it's North of 4k. I've taken two pistol classes, do all my load development with it, and carry it daily. Cleaned it maybe 3x in 4 years and the only malfunctions I've had was when I was load developing and it was all under powered. I'm extremely happy with mine.

I have had mine for 2 years, shot probably over 5000 rounds, ran it in a course and have never had a malfunction or experienced this problem. I do keep it clean but will go about 500 rounds between cleanings.

WD-40 IS NOT A LUBRICANT.
Pistols really need more regular cleaning than most rifles. It's dirtier, and the margin of power for operation is less. I have rifles that I'll clean every 3,000 rounds, whether they need it or not, and not have any failures. Pistols I clean after every shooting session. Usually wipe it all down with CLR, clean the chamber and barrel, then re-lube the contact surfaces with grease. I have an M&P 9 with probably upwards of 9,000 rounds through it. Two failures, one was a bad primer, the other was I believe a mis-feed when it was really dirty. |

WD-40 as a lubricant?
Grab some Slip EWL. I've got over 4k rounds down mine with zero malfunctions. 10 in 2k is unacceptable. |

That is 1 in every 200 rounds or 1 failure every 12 mags. This might be OK for a range gun but it would not make my list for a carry piece. 30 degrees farenheight is NOT "very cold weather" for a firearm at all. WD40 is neither a good lubricant nor a good rust preventative. Personally, I prefer Lubriplate FMO-350-AW as an oil and Lubriplate SFL-0 for grease (where indicated). Mobil 1 syn. is my 2nd choice and something I can get a couple drops off my dipstick in a pinch if necessary. If you are having problems with slide lock on an empty mag "99% of the time" then you need to get that figured out. It is not normal and and not a common problem with the M&P. I am not trying to bust your balls but I am thinking you posted this looking for feedback. |

I will just say what everybody else said. That does not sound like a reliable weapon to me. Not saying anything against the M&P, but maybe you just go a lemon. Or maybe it's the WD40. And yeah, as far as the not locking back, I too wonder if you're not riding the slide stop. I know high thumbs is all the rage but I did it with My M9 and it's hard not to when you grip a handgun like that with some designs. The M&P's isn't nearly as big as the M9's but maybe it's just how you are holding it.
Try some normal lube and quality ammo and watch out for your fingers for locking back and then see how she does. If it continues to malf like that, I'd get rid of it. I also think it's possible that you are limpwristing. You said FTE's. Were they stovepipes? |

I agree with everyone about ditching the WD40. I've seen it lock up some guns after it sits. Turns into a gel like consistency after a while, the cold probably makes this worse.
If you haven't lubed the barrel or slide rails at all in 2k rounds that probably your issue. I have an M&P that I let go for about 1.5k rounds with no cleaning but I did lube it with either slip 2k EWL or CLP before every range trip. It functioned perfectly every time. Any oil I've used seems to burn or sling off by 300-500 rounds. After that you're basically running a dry gun and that's asking for malfunctions, I don't care if its an M&P, Glock or any other brand. Make sure its lubed and I think all the malfunctions will go away. I had issues with the slide stop not catching on mine when I first bought it. Turns out I was holding my thumb on the slide lock, and I do it even worse with my shield. One way I check the mag springs is to insert an unloaded mag into the gun, point the grip toward the celing and push the mag eject button. It the mag pops out of the grip an inch or better then your mag springs are probably good. If they just barely move or not at all, then you need new mag springs and that would be causing the slide lock issue. Oh and +1 on the apex trigger. I just installed my first one last week in mine. I didn't use the enhancement kit, just the trigger and I love it. Much less take up, and a much nicer break with less overtravel. |

Ask me how I know. Used it on a Smith 36. Covered it with the stuff. Got it out a year later and the cylinder wouldn't turn, because the stuff gummed up. That was the mid 1980's. Learned a valuable lesson then. |

I've shot quite a few rounds in cold weather in wi in various weapons and haven't had problems. Something is up that has nothing to do with the cold. At least that's how I see it.
Whoever was saying their friends glock jams more, is that you OP? Again I will say it may be that you're limpwristing. Glocks have a rep for not cycling if you are limpwristing. But other guns will do this too. That's why I asked about the stovepipe earlier. If they were stovepipes, my recommendation would be bad lube and limpwristing. And then I bet you're riding the slide for the non locking back of the slide. All stuff that can be overcome relatively easily. But of course I could be wrong and maybe there is something wrong with your gun. You could have someone else shoot it that is a gun guy. |

WD40 is causing malfunctions, not the other way around. For fucks sake, in the age of the internet, ignorance is a really lousy excuse. I use an M&P as a duty gun, and if it malfunctioned in chilly weather up here where it actually gets cold, I'd be fucked. I chose the M&P because it historically has been just as reliable as my Glocks, but way more comfortable and with better trigger options. If it weren't boringly reliable, I wouldnt use it. |

It pushes the water away leaving a very thin, very quickly evaporating oil. Then there is nothing. To prevent rust, WD 40 is the worst thing I can think of. Do you remember oiling your chain on your bike with the WD? Remember how rusty that mother fucker was? |

WD40 is neither a lubricant nor a protectant.
The only reason it hasn't jacked up your M&P is because it has so many stainless steel parts. Just about anything else would be better. Even vegetable oil.
And yes, the M&P is an outstanding firearm. |
