View Full Version : Is it "legal" to modify the 10 round magazine?

I just picked up my G19 last week and the 10th round is almost impossible to get in there. The slide is also really slow to pull that first round out because it's so tight. Is it legal to modify the inner part of the magazine to just give it slightly more clearance? I'm talking about .050"? I swear you couldn't fit a hair between the magazine and the tenth bullet.

Let the magazine break in. It will work fine. I usually load my new mags with 8 or 9 rounds until they feel broken in. It doesn't take long.

i just fired my new g17 yesterday and i thought i had the same problem..but really i had ten bullets in my magazine it looks like it has 9 inside but i counted how many put in and shot out and i counted 10...i had to use the magazine loader in for the 10th bullet...But even if i put in the 10th one it shows on the magazine indicated that it has 9 but really it had 10...i wouldn't mess around with the magazine because if you modify it probably would give you feeding issues...

Mine shows ten when I have ten in it. I was also using the loader to get the tenth in there. With my hi-power the magazine will go down almost half a bullet beyond it's full capacity... That's why I thought it was so strange.

Glock mag take some time to break in for that 10th round. Don't mod it.

I don't see a problem with filing down the follower. As long as it doesn't fit 11 rounds, you're good to do.

However, opening G19 10-rd magazine is a royal PITA.

Yup my xd was the same and after letting them sit with 9 rounds and the slide closed for a few days the 10th one fit easy(er).

Don't mess around with the magazine, just use your loader for your 10th. It was hard to get the 10th rd into my glock 19 mags as well but after a while it'll break in a bit

"legal" yes.

Recommended -no.

On my M&P 40 I cut 1/2 spring loop to make the mags take 10 without an issue.

I let my Glock mags sit for 2 months fully loaded and that eased the tight fit.

Legal yes. Recommended no. Got it. It's just amazing how tight they are. I really appreciate the feedback from everyone.

I'd be concerned that after it broke in you might be able to fit 11. They take a while to break in.

For my SIG P226 in 40S&W.
I have replaced the followers for ones that were for twelve round stock mags.
The bottom of the followers are not quite as long,
The magazines now have enough room for about ten and a half rounds,
I have ran over 1500 rounds thru my magazines without a hiccup.

While I can't testify to the spring diameter of all magazines, most I have seen have had a dia. of about 70 thousands. Even removing 1 complete coil would only increase the depth the follower can go by 200 thousandths max.

A mag loader will help you get that 10th round in, and will help break in your magazines a bit quicker

Yup, it will get looser.

Considering yourself lucky you don't have the opposite problem - I have a 10-rounder that can easily accommodate an 11th round. Gonna have to get the soldering iron to fix that.

I suppose it would depend on the gun. I bought a couple 10-rd AK magazines that were able to take 11 easily. I "fixed" them, but it turns out I didn't need to since I'm running a featureless rifle. :facepalm:

In this case it's a handgun. So if I want to assemble it, I'm going to have to modify it and insert a block down there.

Maybe I'm wrong, but it sounds to me like you legally aquired an 11 round mag. I don't advise breaking any laws, but why would you intentionally reduce your mag capacity?

Just shoot and cycle the magazines more and you'll be fine. When not shooting let them sit fully loaded and that helps a bit. I have x9 10rd G17 mags and all are a mix of broken in [mainly the original 2] and 7 others that are a mixture of extremely stiff to just getting broken in. It's a serious pain in the beginning, but it gets better over time.

yeah, either cycle the mags more to get 'em broken in, or develop some stronger muscles in your hand. No need to tamper with the magazines. I have 8 factory 10rd. Glock 19 magazines, and never had a problem getting 10 rounds in 'em, even when they were new. :rolleyes:

Thanks guys. It's not that it can't be done. Like I said, they are just extremely tight. I've decided to just leave them full for a while to break them in. I love this forum :-)

Leave it loaded for a few weeks or months in the safe with the full 10 rounds.

I have a crap 10 rounder I use when I let newbies shoot my Glock 19- anytime I don't trust someone not to jack up the feed lips on loading :D

I left it full for 2 months and you could load the 10th round by hand no problem (still stiff but doable). That was about 10 years ago- loads nice and easy now!
