I've been using a Maglula Uplula loader (it came in the range kit) and it needs a pretty good push to get the 10th round in. Handloading the mags is difficult as the spring is pretty strong. Also, I find the 9mm Luger rounds tend to bind on the plastic follower. Will this get easier as the mags get broken in or is there any mod that can make things faster and less thumb destroying?
New M&P9 Mags hard to load

if the mag itself no problem, then yes. I got this on my new m&p and Glock mags. there was once though, when I bought 5 new mp9 factory mags, one of them was like that, but worse. even hard to put in 7th round. went back to store, opened it up and found the spring was installed backwards.

step 1: take mags apart
step 2: cut 1.5 coils off mag spring and bend bottom to match oem
step 3: remove material from bottom of follwer
step 4: re-assemble and fill to 10 rounds and let sit for a few days
step 5: enjoy easier loading of said mags
There are instructions online for just this that I followed

For god's sake don't cut mag springs, that's just begging for a gun that doesn't work. Load them and leave them loaded, if you can't get the last round in (not a problem I've ever experienced in any of my 8 mags from 3 different generations) modify the follower legs. Without decent mags the gun will not feed, rebuild your mags when needed or every 2 years for most folks - heavy users rebuild every year, and do the followers every rebuild, after 10K they look like crap, and can fail to hold the slide open. Shipping is the biggest cost of parts for the mags, so order enough for a couple of rebuilds while you're ordering.
The Force is strong in this one.
Compression and decompression of springs is what causes wear. Leaving them loaded for a thousand years will not change anything.
Where did you manage to find those??This topic come us fairly regularly. First of all, DON'T cut the springs.
Disassemble the mag and remove the follower. Place a piece of sand-paper on a table. Take the follower and move it in circles on the sand paper until you have removed enough material so that you can no longer see the small curves on the bottom of the follower at the front and back. Re-assemble magazine. DONE!

Please listen to these people. And me as well.
I had the same issue.... but I left the magazines loaded for several weeks and I no longer have any issues. Please don't cut anything...

I have cut springs and shaved followers in 5 of my MP9 mags and have had no problems at all. Bunch of worry warts if you ask me lol.
Eventually I will be picking up some 17 round factory mags from the US and block them to 10 so I can add base plates and a magwell for IPSC.

Magazine springs will "take a set" when placed into service. It doesn't weaken the spring but it does shorten it. This is why loading your mags for a period of time is a good idea. New (never inserted into the magazine body) M&P mag springs are more than twice the length of the magazine, (if you've replaced them, you know this) in service springs are closer to one and a half times the length after a week of sitting loaded. Cutting springs is asking for failure, unless you know the design spec of the mag. I've been running the same M&P9 for 8 years, and generally abused it through 55,000 rounds of trouble free operation - zero failures not related to crap ammunition (my third M&P and second in 9mm).
