M&P 9mm 10 round Magazine

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

$26! Man.. I'm jealous, even though my Uplula was the best $40 I ever spent. Over priced at a local gun store, but still it was money WELL spent. Can load mags ALL day now.. just have to be able to find ammo to load them with! haha.
 
My 40 came with an Uplula, and yes I would have bought one had I known how wonderful loading magazines is with one...
 
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 bought my first M&P .40 in California. Ten rounds fit in the magazines by hand with no problem.

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.

After trying for weeks to get the 10th round in and the mag and/or to insert a fully loaded mag when the slide is closed, I decided to sacrifice one magazine to a try a few experiments.

I tried first removing 1 then 2 then 3 loops. While this does help, slightly, the last bullet still needed to be forced into place. The fix was to remove (file then polish) about 1/16th from all 4 corners of the bottom of the follower. After cycling a few complete 10 round through - without an issue - I then did the mag mod (3 loops, 1/16th off follower) on the rest of my magazines. Now I can hand load 10 rounds though I still use the uplola. There is still no way to push an 11th round in.

While in the magazine, I used the opportunity to polish the sides of the followers and add a little lubricant. Well worth effort, for me that is.

hi..
new mp9c, 4 mags. all difficult to hand load. let the mags sit for two weeks with 9 and 11rds in the mags (all rounds inserted by hand). after two weeks, used uplula to load 10th/12th rds. takes a bit of finess (trickery?), but the last round will go in. now only two mags refuse to load to max using just thumb/finger presssure. the gun fired properly with max rds in the mags. did not notice any difference inserting and firing with full or one-round less in the mags. also daily cycling the slide by hand to "loosen" the action (my new unit is way more stiff than the LGS rental mp9c - which has 10,000+ rds thru it). but the mags will eventually accept the full load (have not the proper tools to cut/polish steel).

cheers, ya'll
 
10 round mag for M&P Pro

I have these 10 rounders for use in New York. Look on You-Tube about the fix for this! If you are handy & own a needle nose pliers, then FOLLOW THE YOU TUBE details on how to open the mag. & snip the wire at the bend, also sand the plastic 'legs' on the insert. I also filed the sharp edges of the wire. Reassemble & use the Uplula loader...& ALL IS WELL...a 10 round mag. that snaps in easily!!!
 
is this the forum to discuss converting FS mags to 9c?

have two 10rd mags for full size mp9. the base plate is actually an extended device substituting for the longer 12/15/17 magazine. the plate is different from the standard 9c mag. where can i get flat or finger rest baseplate for the full size mp9 magazines?

thank you !!
 
I had great difficulty getting 10 rounds in my M&P40C mags when they were new. This was before I got an Uplula loader. I kept the mags loaded fully for a week but they were still to hard to load. What I did was load & unload them a half dozen times & that helped a lot & then keep them loaded with as many as you can get in.. Didn't help the fingers any, though, lol. They were sore for a week. I believe the springs need exercising both in compression & decompression. Then I started to actually shoot the gun at the range. Even though it's no longer hard to load by hand I still use the Uplula. I'd be hesitant to make any modifications on the spring or follower. You might run into feeding problems once the springs loosened up.
 
Has anyone been able to load 10 + 1 in the MP9? Like previous poster said, it won't load a full mag with slide closed, much less the 10 + 1 as advertised.

haven't had that happen. mp9c. 10 and 12rd mags. about half the time load mags with uplula, half by finger/hand. no probs with 12rd, last round is kinda tight on the 10s, but they are range only. with one in the pipe, re-fueling the mag after slide in battery, nothing seems to hang or feel different from open slide mag replenishment. so, not sure if my experience is the norm, or yours.

cheers
 
These are actually supposed to be 12 round magazines. but Smith and Wesson is in Massachusetts which is forcing them to go to 10 round magazines.

Since the 9c will accept the full size 17 round magazine I bought one of them. Disassembling the 2 clips I found that the spring and follower in the 10 round clip is exactly the same size as the one that's in the 17 round clip. No wonder you can't get 10 rounds in the clip! So I cut the spring down to where it's commensurate with the size of the clip.

You may say it's illegal to modify the spring, but I say it's unconstitutional for Massachusetts to arbitrarily limit the size of the clip. Besides, I live in Ohio where the 12 round clip is legal so Massachusetts can kiss my ***.

It's still hard, but now at least possible to get the 10th round in the clip. I suspect if I cut the follower down it would be easier. Maybe even possible to get 12 rounds in the clip, but I've got the 17 round clip anyway so what the hell.

Smith and Wesson needs to get smart like some of the other gun manufacturers and move out of cukoo land to a state like Tennessee or Texas.

This has nothing to do with S&W's location in Mass. It has everything to do with state law covering the person BUYING the magazine. If you reside in Mass, then you are restricted to 10 rounds, just like us in CA unless you are exempt in some fashion.

There are other states with mag limits. The limits, if any, vary by state.
 
The only resolve I came to that works is to shave the feet off of the followers until you can get the 10th round in. I did it with all my offending mags and now can get the 10 rounds in easy. The problem that S&W could fix if they had a mind to is simply correct the design of the followers. The Follower bottoms out on the mag and there is nothing you can do but either load 9 rounds or shorten the depth of the follower. The fix only takes a minute or two with a file.

Take care

I bought my 9c in Ohio about 2 years ago and it came with the 10 round clips. At that time, and up to about 6 months ago, there were no 12 round clips available anywhere in the known universe. Now I see there are some. Halleluiah! I'm gonna buy me a couple.
 
Right. If you currently live in an non-restricted state, you can buy them as big as they make them. Get a few more 17s and an XGrip or two.

Here in CA, I recently bought some handguns that don't have 10 round mags available. The FFL had to block them down to 10.

For those struggling with the 10 rd mags I have found the only solution is to trim back the bottom of the follower. Cutting the springs won't help much. The problem is the follower bottoms out on the base. I took a file to mine and removed material from the base of the follower until the rounds loads with ease. Why Smith changed to the newer followers is anyone's guess, I suspect they changed suppliers.

Take Care
