9 Rds. in a 10 Rd. Magazine ?

[Johnny Guitar]

I recently purchased the M&P 9mmC. Have not shot it yet, but the ergonomics are great. I'm a lefty and the ambidextrous features sold me. I went into Turners Outdoorsman to buy a Glock and came out with a M&P 9mmC.

I cannot load 10 cartridges in the 10 rd double stack magazine (this is California, only 10). I can only load 9 rounds. I'm using a Uplula mag loader but there is no room for the 10th rd.

Can anyone help?

I just got an M&P 45 a couple of weeks ago that at first had really hard to load 10th rounds and then would just stop accepting the 10th round all together. I shoot in USPSA so I have 12 mags, this happened to every single one by the end of an all day match. I took them apart, inspected them, rebent the springs a little where it looked like they were binding. Nothing really seemed to completely fix the issue and it would rear it's ugly head and cause me to have to eat time really slapping in my reloads because everything was too stiff.

I ended up getting out my leatherman and just clipping off the bottoms of the springs. So if the spring is completely unsprung, I would start about two rungs down (one half to three quarters of an inch) and cut it off. Then I would bend the spring to a 90 degree angle again as it looked stock and rebuild the mag. I've done this on probably 8 of the 12 mags and I did this during the match and have used them in practice since. I've never had an issue.

I was nervous at first as I figured that S&W must have a good reason for the amount of spring they put in, but when I went on SSS and saw that their +3 round baseplate uses the stock spring and I'm only cutting off enough to reliably feed the 1 round that it should always feed. I stopped worrying. I imagine this could be an adequate resolution for the other calibers as well.

This is a fairly common issue, and not just with M&Ps, or even S&Ws. It seems a number of pistol magazines have this issue.

Before you cut the springs, I would suggest loading the magazines with 9 rounds and let them sit for a couple of weeks. You should be able to load the 10th round after that.

I would be concerned about cutting the springs because over time, they may lose a little tension and not feed reliably.

Our respective governments that limit magazines to 10 rounds threaten the companies with fines and jail for the company execs if it is possible anytime, anyway to put 11 rounds in one of the "PC magazines!" So why do you think the companies err on the side of caution and put an extra coil on the bottom of the springs? Wouldn't you? Do you understand why the companies can't just tell you to clip off the extra coil? Do you expect any state that passes "PC magazine laws" to be reasonable about anything to do with guns or magazines??

I've found the last round always hard to get into a new mag, but you can force it in. I use an UpLula and put some beef behind it to really force that sucker in there.

Once it gets in the first time it is much easier the next time. It may be psychological, I don't know.

I think the UpLula is the best invention since sliced bread...especially for those of us with little girly hands!

I have the 300 whisper, it came with a 10 round magazine and when I first loaded it, I only got 9 rounds in. Not matter what I tried... Not a big deal, shot the 9 rounds and loaded again, this time 10 went in, no problem at all...

Glocks have some seriously tight magazine! Even tighter inserting and locking in place when they are full on a closed slide.
