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?

They will eventually take the 10 rounds, but it will then be very difficult to insert the magazine into the gun if the slide is forward. Sometimes, the fully loaded 10 round magazines induce a malfunction. I dodnt know why they had to cut it so close on the 10 round mags. The 17 round mags have some play when fully loaded, the 10 round mags are just too damn tight.
 
Simple: Your state government will charge the company with a crime if it is possible any way to somehow get more than 10 rounds in the magazine, ever.
Therefore, the required magazines are too tight for proper functiioning when new.
Aren't you glad your state government is helping design your guns? :rolleyes:

I have the same issue. The speedloader will NEVER load the 10th round. You may be able to get it in by hand, but I just go with 9 rounds. When the 10th round is loaded, it feels funny when loading it into the handgun.

Also, if you need additional mags, check HERE

He did not mention where he is from, but I figure its one of the big 4 when it comes to nanny state anti-gun laws (NY, NJ, MA, CA). Gawd do thost 10 round mags suck...
 
I know this will be a difficult concept to understand but here you go! If you can't get 10 rounds in the mag,load 9 put it in the gun, rack the slide to load a round remove the mag add 1 round and you now have 10 rounds in the gun! I'm betting the idiots in the goofyfornia legislator figured that if they allowed a true 10 round capacity magazine, that a person could actually load 11 rounds in the gun! Just my theroy and may be incorrect.

:confused:

Sorry, but I don't think your theory works well. If the law says that a 10-round mag is the max, then it's the magazine that they're talking about.

Additionally, in IDPA, the rules state that the gun shall be loaded to the Division capacity so technically it's a no-no to start out with only 10 rounds total in a 10+1 gun.

FYI, my Sig P226R 10-round magazines take 10 rounds easily. I have a bunch of 9mm & 357/40 10-round mags for IDPA so I don't have to count and/or worry about screwing up and load 11-rounds and have to take a penalty. OTOH, when not in competition, it's loaded with 15 rounds of 357-SIG.
 
same issue here. I use the uplula and when i try to push down after 9 rounds, it comes to an abrupt stop halfway down for the insertion of the 10th round. This abruptness makes me think that the spring is at its maximum compression and it won't be possible to ever fit that 10th round. I have the matte mags with the gray plastic follower.
 
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.

OK, so here goes the story. I called S&W and asked them about the 10th round in the mag and they said its a stiff spring and will loosen as you use the gun. Eventually you will be able to put 10 rounds in the mag. I am in NJ using the matte mags with the grey plastic feeder/follower. Blasted 150 rounds through it last night, still not even close to getting in the 10th round. In case you are all wondering, I was using the green and white box of Remington UMC 115 grain and not one single problem.
 
I've had my 9c for 15 months and I still can only get 9 in the magazine. I just except it.
 
Yep, its not gonna happen unless you happen to get a lucky mag or modify the mags somehow by cutting the spring or filing down the follower. Dunno if that's ever been tried, but definitely not recommended though.
 
Mine were next to impossible to fit the 10th, but now after 500 rounds through it, it is starting to get a little easier to fit the 10th.

IDPA issue? Min load = max mag(or 10) +1 in pipe.
 
wow. great thread to come across . have had mine for 9 months, only get 9 rounds in it, was wondering about it all the time, but just accepted it. Figured the spring was very tight and would loosen in time.

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...
 
Move to Texas my 10 round mag friends! Problem solved. :D 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.
 
I had the same problem with the 12 round mags for my 9c and could only put 11 rounds in them. It is not the spring, but rather the follower is too tall. I disassembled them, ground off about 1/16" from the legs of the followers, making sure there were no burrs from the grinding and a slight bevel, so they won't hang up. They now take 12 rounds with no problem.

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.
