what does part #236 do on glock mags?

[bong]

ive asked this a couple times around in several topics.
#236 can be seen at
www.wargameclub.com/gun-folder/g18c-install.htm

all the way at the bottom. so far everyone ive asked about it has no idea what its for, but i think its a thumb grip of some sort. I know where to place it (back of the mags where the holes are), but it doesnt stay.

ahhh having a piece of my mag laying around is eating away at my brain...

I don't have that piece on my mag.

Does it snap on over the valve? perhaps it's something to cover it so it can't be fired? An additional safety of sorts.

it goes into the back of the magazine.. it fits perfectly into the holes (square form, has 22 23 24 25 going clockwise). Tkae a look at the mag and youll know what im talking about. it fits in fine, but doesnt stay. super glue? :

It serves no purpose, as far as I can tell. It only comes with the hicap mag, why I don't know. Mine is sitting in the mag box still....

the gun looks cooler with the back piece on =)
