Default HOW DO YOU FIX A "TOO TIGHT" MAG?

I have a factory mag for my 1911 that is too tight. It kinda binds a little when I load it, and doesn't feed all that well. It looks like all the others I have, but doesn't feel the same

I'm about to chuck the thing, but I wonder if you mega-smiths know how to "open it up" or if it's even worth it.

UPDATE: To eliminate the confusion others have mentioned below: The problem is getting the rounds into the magazine, not getting the mag into the gun. Sorry

As an amateur... I would use machining blue.. Or a black marker on the mag. Insert find where it touches and remove metal with a light abrasive.
Smiths. Don't knock me!.. In before the pros
Edit.. Maybe you are referencing the feed lips... No idea if so

Most likely not worth trying to fix for as little as new mags cost.
You would have to make a pair of wedges that will fit inside the tube and allow you to swage it from the inside if it's a width issue.
If could just be a bad follower too.

Make sure the grip screws are not sticking out too far inside the mag well.

Mark that magazine some how so you know what particular mag is giving you pro-blame-ohs.

Find another 1911 of same caliber, that might be difficult I know, see how tight the magazine in question fits that 1911.

Take a good look at all the interior & exterior magazine surfaces. If you detect rice & fake fish soup lunch slime then it's a sure bet you have a Chee-Na counterfeit.

OP, did you try cleaning it?

I know that it will probably not help, but at least you can get the guts out and see if you notice anything different inside rhe mag body or with the follower... or with the spring...

In any case, like Randall said, they are not expensive enough to troubleshoot (assuming you have a standard GI mag.

I find the Grip Screw Bushings to be the usual culprit.

You can check by using something wide and flat - like a cut up (expired) credit card - to feel for protrusions

I remedy by using a coarse or medium Eze Lap Diamond Hone to dress down the offending protrusions in the magazine well
This will remove finish inside the well, of course, but I'm not too concerned with areas that are not readily visible.

Remove the slide, but leave the grips attached, so you are sure to dress down anything that is intruding into the mag-well,
but as noted - it's usually just the Grip Screw Bushings.

folks...so much is in the wording...
I don't think OP is taking about inserting the mag into the magwell of the pistol
I think he's talking about putting bullets into it, and then feeding when shooting

Hence my reply.
Most of the other replays are way off base.

AR mags get filed down. Had to do that with ASC Grendel mags, too wide.

I'm betting it's AR15Barrels' guess. Would like some clarification from OP.

The mags that came with my Springfield 1911 LT 9mm had bad mags. When I load more than 5 rounds the most bottom rounds would get stuck with the follower. The mags were the stainless Metalform mags with the rubber bumper pads. The current mags that comes with SA 1911s looks like Checkmates.

The OPs post is not worded clearly.
I'm reading it as when the mag is full it is tight in the mag well.
Cheapo mags can expand when loaded, these often don't feed well.
My original thought was to recommend cleaning the mag first.
Then I re-read it as the mag is too tight in the mag well.
This can easily happen if the grips are changed and the grip screw holes are slightly deeper, allowing the tightened screws to stick out inside the mag well, hence my comment.
When doing these diagnose-my-gun-problem threads, it is common to assume the gun is factory original with no changes.
This is often not the case.

There's lots of helpful people in this thread, OP needs to update us with more info.

Until then, who knows?

OP:
I take all of my mags apart and clean and polish the surfaces.
I've had way too many mags that catch rounds and followers on sharp surfaces not to.
It is very little work for something that will virtually last a lifetime.
The best example would be my Ruger Mark III 22/45. You couldn't even pull the load button all the way down on almost every single one. Now they all run fast and smooth.

check if it is the internal dimensions of the tube or the follower. You can shave down the follower, but I'd get a new mag if the tube is out of spec.

I had a 1911 magazine that would stick. The gun still functioned correctly with the mag: It just would not fall free.

I removed the follower and spring, found the high spots, and hit them lightly with a ball peen hammer. I got the mag to work. Now, 5+ years later, I cannot tell which mag I fixed.

ProtectThe2nd is right. The problem is "getting the rounds into the magazine", (it is not "getting the magazine into the gun").

Sorry for the confusion.

Sometimes, things require a bit of break-in. The follower or the spring might be a bit off, or there could be a burr inside the mag tube.

I would take the mag apart & clean it. Load it full, and let it sit for a week or two. In a safe location, cycle ammo through the mag/firearm system.

I number the bases of my magazines. If I experience any type of malfunctions, I note which magazine was involved. Good luck.
