M&P 9mm 10 round Magazine

[Houdini1953]

Move to Texas my 10 round mag friends! Problem solved. Actually I bought 2 of the 10 round mags strickly for reloads in IDPA. Same story as everyone here and the 9 was a you know what to load, 10th round, forget it. SO I called S&W, told them my issue. Sent them the mags back and they sent me 2-17 rounders. Problem solved. Now when I reload mags for IDPA, I have to count bullets.

Actually you don't have to count rounds because all you have to do is look at the magazine and it clearly shows how many rounds, but in competition you might want to load only what you are supposed to by setting up boxes that have just the amount required for any event!

I just picked up a new M&Pc 9mm last night. Weapon has the 10-round mags and I was able to load both mags with 10 rounds by hand. Tenth one was not too difficult. But the mag did not completely seat well when the slide was forward (I was goofing around with it and did not want one in the chamber).

I guess I could have slapped the mag harder, but did not want to force it and maybe break something. Maybe that's an irrational fear

But is sounds like this gun won't handle 10+1 in a stock condition, even after the springs break in?

I put 1000 rounds through mine since I posted this thread. The 10th round is still a little difficult to get into both mags but it does fit when using a speed loader. However with the slide forward and 10 rounds in the mag it will not click into place. Only with 9 rounds will it click into place nicely. Also noted I called S&W and asked about the slide stop being difficult to release with just my thumb. They said it is a "Slide Stop" not a "Slide Release". With the mag ejected and 1000 rounds breaking in the gun I can now use the "slide stop" as a "slide release" but it is a little tight. When a loaded mag is inserted with the slide back the slide stop now becomes a slide release with ease. Now, when you insert a loaded mag and slam it into it with the slide back sometimes it auto loads and releases the slide stop. I also called S&W on this after watching videos on YouTube and they told me it is an M&P gun, imagine you are in a gun battle and you need to load a new mag fast! The slide lock is meant to auto load the round, it could be the fraction of a second between life and death. I am in the air about that with many others confused if that is just a flaw in the gun. But, then again S&W came up with a good argument of why it does that. My opinion is if its meant to do that then why do you have to SLAM it in.

Well, throughout my years of shooting experience, I'm not going to trust how many rounds are in a mag by simply looking through the holes. I have seen on a few occasions, rounds double stack in a magazine on one side.

I keep a loaded mag in my safe to try to loosen it. Someone told me not to keep the mag loaded, it would prematurely wear out the spring, but I don't think that is an issue here...

don't worry... springs only wear with repeated cycling. storing a spring compressed should not damage it significantly. i'm in the habit of keeping 2x 10-round mags filled in the safe with JHP rounds for zombie invasions. I use my other 4 magazines for range use and rotate them once in a while.

New update, I was showing a friend my UpLula speed loader and I said I can't get the 10th round in my mag. He says lemme see that 10 round mag and that UpLula. He pushed down hard and wah-lah the 10th round went in with no problem in both mags. I put 350 rounds through the gun in case you were wondering. So all you have to do is just push hard on the 9th round and the 10th will fit. Its fits just perfectly. Don't force it, just apply steady pressure.

this is pretty much the trick. just drop $20-30 on a LULA and don't look back. you might have to stand on it the first few times to get the 10th round in, but it will eventually work.

here in Kalifornia, state law is 10 rounds on the magazine, but you are always allowed the +1 chambered if you so choose. inserting a 10-round magazine on a closed slide can be a problem though, so you have to be extra-vigilant when loading up if you don't slap the magazine hard enough. i learned this the hard way a few times during training classes... i don't think you should have malfunctions due to the 10-round mag being jammed up against the slide, but you WILL have malfunctions if the magazine isn't seated properly... e.g. BANG -- click.

while it's an extra step, i slap the magazine in and check/slap it again before i holster, just to be sure. one of the accommodations we have to make for our awesome nanny-state!

Had same problem with the 10 round mags for my MP45f, got a Lula loader problem solved.

Greetings from New Jersey… After upgrading with the apex tactical trigger and sear, the storm lake extended and ported barrel, the Sprinco recoil spring and the Hogue finger grip. I cut 3 loops off the spring of my 2 mags and filed down the guide. So much easier to load all my rounds and the 10th is like nothing. More important to me is I could insert the clip with the slide back or forward. I guess I should say Hello because I am new to the forum and let you know I just got my firearms license 2 months ago and yes my M&P is my first gun. I have put about 1500 (trouble free) rounds through my full size M&P 9mm and I am in love... 500 more rounds waiting for my day off on Monday.

I just cut 1/2 loop out of the bottom of the spring and rebent the bottom and now all my mags work great. No problem with the 10 and will not even come close to 11. It also cleaned up the "hard to seat when full" issue.

 

[Canuck44]

Yep, manufacturers are so afraid of the 10 round laws in the Occupied States that they make it impossible to get that 11th round in there by making it impossible to load 10!

I know it's possible in some pistols to use a 10 round .40S&W magazine (a legal magazine even in the OS) and get 12 rounds of 9mm working. It's a magazine restriction, not a pistol restriction. And, really, unless you hold up the local liquor store no one cares.

Either that or we are just seeing poor quality control with a spring supplier sending the manufacturer springs that are to stiff and the manufacturer not carrying enough to insist on better quality control. I suspect the latter.

Take Care

I never had that problem with non of my M&Ps but always had that problem with my Sigma and my SD. I just forced the extra round in the mag and let the mag sit fully loaded for a week or so. After that, it should be easy to fit all 10 rounds inside the mag.

 

[VMaxSplat]

A ten round, double stack 9mm magazine is what should be against the law. Goofy ***, liberal politicians...

 

[Syke001]

Any one have a extra 15 round mag for m&p 40 cal

 

[Syke001]

Got that right vmaxsplat

 

[Houdini1953]

I bought the extra magazine extensions for my Glock 26 which holds ten rounds and makes it feel a lot like a Glock 19 so that all my fingers hold the weapon.

It took all I could do do put the 11th round into the first two magazines that I used now after several trips to the range all three hold 11 rounds but should hold 12 so now what I do is use my UPlula and keep them all loaded then take the rounds out by hand and then reload and eventually I will be able to load 12 rounds into them!

Or you could shorten the spring and even shave off the bottom of the follower by about 1/4 or 1/3 using a grinder, it is pretty simple for me but I am just a redneck from Tennessee!

 

[MP1SG]

My 40c came with three (3) ten (10) round magazines. I loaded all ten rounds without a problem. I bought 2 more 10 rounderrs from Greg Cote (great fast service by the way) and loaded them with ease. Sounds like this thread is equal with easy to load 10 round mags and not so easy to load. Just a luck of the draw i guess.

Sorry for reviving an old thread, but I thought I'd post a more current update. I received my M&P9 a few weeks ago, and I'm in California so I have the 10 round magazines. I don't know if they're making the magazines any differently now, but I use the uplula speed loader and I have little trouble loading the 10th round in the magazines. I have to push down quite a bit for that 10th round, but it's never really a problem.

Calif 10rd mags

I recently purchased the 9c and use the UpLula loader to fill the magazine with 9 rds easily but have to force load the 10th rd by hand. Difficult but it can be done

 

[sdeeut69]

I just got my brand new M&P 9mm with 10 round capacity. I never shot it yet, but I did load the magazines. I can only fit 9 rounds in both mags, even with a UpLula speed loader only 9 will fit. This is my very 1st handgun, so forgive me if this is a stupid question. Am I doing something wrong? Or is the spring just so new and tight 10 rounds will fit after a few loadings?

Mine was VERY difficult at first. that last one was a B*TCH! The first time I had it at the range and tried to load it I realized I couldn't do that all day. I ran up and bought the Uplula and it was SO MUCH EASIER.. but the last round is STILL difficult to get in. Wait until you try and put that mag in. You have to slam it closed with your palm. But I haven't had ANY issues with misfeeds or anything from it. It shoots great and I love the gun. But yes, that last round is a pain.. in fact on my mags even the first one is very difficult because of the way it wants to roll into the mag.. it's VERY hard to get straight.. then 2 through 9 are great and 10 is near impossible. But that Uplula will help you get it done, you really have to push down on it HARD but you'll get it. Good Luck!

I have the same problem. I saw a video whith Hitchcock45 who said that he had this problem with a Glock and he decided just to leave the last round our of the magazine. I'm not as happy with that idea. Besides, Hitchcok45 is a better shot than I am- I need all the rounds I can get. Also, I hear there are some performance issues when you crowd a magazine.

Uplula was the best 26 dollars I ever spent. My 12 round mags are damn near impossible to load without it.
