Does anyone know how to disassemble this magazine? Mine is old and gummy, but otherwise in excellent shape. I'd like to take it down to thoroughly clean it, but don't know how. The floorplate is pinned and staked, so that's not an option.

Thanks,

I have two of those, and have never tried to take them apart.
You could try boiling the whole assembly for an hour, then soaking it with alcohol to remove the water that doesn't evaporate off the surface.

Thanks. I have an ultrasonic cleaner, but I don't know what cleaner I would use to dissolve the .22 bullet lube.

Fairly warm in an oil bath will gradually remove the “waxy build-up”. Allow to dry, repeat. Needn’t be perfect. Looks as though the follower is metal ... so shouldn’t be a problem.

After it’s good-enough, the UltraSonic will remove debris and dirt not embedded in the remaining wax.

However: in your place (with a different conversion kit), I ordered some GSG magazines. The GSGs have run all of my conversions: seven examples of five models. Only disadvantage is that they engage the slide-stop on my Kimber kits ... those kits are not intended for lock-back-on-empty. Having no Colt kit, I do have one Colt kit magazine; it appears very similar to the GSGs. The GSGs are not too expensive (used to be much less ~$15); my thought is worth a try compared to a long and laborious effort to clean a magazine when the spring may also be near end-of-useful-life.

You disassemble the magazine by driving the pins out at the bottom. They come out easily. The baseplate is under spring pressure so be for warned. Replacement magazine springs for Colt or Metalform magazines can be purchased from Marvel Precision.

Thanks. Have you done this on the same type of mag? As I said in the OP, the pins are staked, so it is not as if they were intended to come out, and it's not something one can do repeatedly without significant wear and tear.

Blast it out with spray solvent. Use electronics cleaner to protect the finish, not brake cleaner. CRC electronics cleaner is a good one for sensitive items. Failing that, just use mineral spirits - soak for awhile, swish around in the solvent then blow out with air or let drain/dry. Same for any mag you don't want to take apart.

I've just taken mine apart. The pins come out easily. These are the replacement magazine springs that Marvel Precision sell. They are identical to the originals.

Yes, I've done it.
Nice, thanks. Maybe I'll try it. Meanwhile I just splashed a little Hoppe's No. 9 and the follower freed right up. I bought this '60's vintage Colt .22 conversion kit and I don't think it was ever cleaned!

I have 2 Colt .22 Conversion Units and the GSG magazines work perfectly in both. Just another option for extra magazines that won’t put you in the poor house. As I’m sure you are aware original OEM Colt magazines are expensive.
