Magazine Tool for SIG Mags?

I'm trying to open my SIG magazines and I could only get one of ten to open with the conventional "press button/slide base plate forward" method. I'm a big guy and I really leaned into it too. I used all the leverage I could muster and these stubborn base plates are not budging. When I searched for a SIG magazine tool all I saw were Glock magazine tools. Despite the disclaimers about not working with anything but Glock mags I'm gonna give it a try.

Meanwhile, back at the ranch... Why are there no SIG magazine tools? With SIGs lasting as long as they do, folks must have a lot of magazines that need care and maintenance.

On a side note, my dumba55 FFL pinned my super-dangerous "hi capacity" mags at NINE rounds instead of ten rounds. "Oh, they just need to break in..." ShÏtforbrains jack wagons don't seem to realize these mags are eight years old. They're broken in as much as they're ever going to be. Lazy punkazz tossers.

Never heard of Sig Mag-tool and never need any tools to take them out to clean either ..
Something with small pointy should work
I use this :

I usually just use the end of a cleaning brush or q-tip. I wonder if the pinning of your magazines to a safe capacity could be the culprit for the difficulty you’re experiencing?

I just use a Glock Armorer tool on the button and slide off the baseplate, taking care the spring doesn’t launch into Low Earth Orbit.

What kind of mags are you disassembling, exactly?

I've always used the point of a M193 round to depress a firing pin retainer or base plate retainer.

Get one of these and keep it handy.

The handle will depress the magazine floorplate release. Brush out the magazine tune using the brush....no lube.

The one on the right looks to have a welded floorplate,

First, I would wonder if the pinning of the mag is to blame.
Second, are you sure that you are depressing the button far enough?
Sometimes it looks like the button is down far enough but it actually needs another 1/16" or so.
I usually use the end of a cleaning rod with no jag on it.

I don't know what I am talking about here but I am wondering if the pinning of the mag requires different mag springs.
If I were you, I would take the mags back to the monkeys that did the pin job and have them sort it out.

Can you post a pic of how they were pinned, or riveted or whatever to limit the capacity?

Oh, I've done that! With a Glock magazine I carelessly yanked off the baseplate and the spring launched directly into my forehead. No damage to me or the spring, but quite a surprise, and a lesson learned. Could have been my eye. First words out of my mouth were, "Geez, I'm officially a dumbazz."

I will post a pic if/when I get one open. I shall modify the spacer to actually allow 10 rds.

I inserted a Glock armorer's punch to depress the button a full 2 1/2 inches, and even used the inserted punch to apply some leverage. No joy. Once my Glock magazine tool arrives I will commit to opening or destroying one mag in the process. Oh, that baseplate is coming off all right. One way or another...

Is it possible that when the mag was modified the guy put super glue on the base plates to keep people from “un-modifying” them in the future?

If the "press button/slide base plate forward" method didn't work, I am guessing that, as Mpddoud162 said... the base plates were super-glued on.
It might be worth it to try a couple of experiments, such as heating the lower part of the mag and base plate with a heat gun, or dipping the lower inch in a cup of acetone...
NOT AT THE SAME TIME.

I take NO responsibility here. Also, I have no idea to what extent that heat or acetone may damage a base plate. I would just try both methods, sparingly and judiciously. Hint: if the first method works, you won't have to try the second one.

When sorted make yourself up a rod with a tapered point out of hardwood. It is a guarantee that using metal on metal that one day you will slip and put a cracking scratch across that mag base. Make the point of the rod long enough to push that button right in , once in then slide.

Well, the Glock Magazine Tool arrived and it's completely useless on these SIG mags. The geometry is all wrong. So I went back to work on one using just the metal punch plus a few drops of CLP oil, and after jerking it back and forth for about 10 minutes --- VICTORY!!!

Here's a picture of the crude magazine spacer to limit capacity. Nothing more than a crude hunk of hard plastic. I will cut half the stem off and re-install.

The culprit behind the difficulty open these suckers appears to be some glue as the residue is visible once the baseplate was removed.

Congratulations on your victory. The next one should be a piece of cake.
