Maybe a dumb question..
 

So I go the wrong mag...though the mags are almost same dimensions, only the height is off about 2-3mm. Is there bottom pieces that can be swapped out? What's that piece called anyways?

The left one is the right mag, the right one is not, the shake is preventing it from being fully inserted.

Sorry for the troubles,
Ben

You need to add in brands of both mags and what pistol they're meant for.

I'll guess one is KWA MK23 but what's the other?

oops sorry, you're right, it's KWA HK MK23 SOC and other is KWA HK USP

I didn't notice it was so fuzzy, here's another

if you can even order that part from kwa, by the time it gets to you, it will probably cost as much as another mag... just sell it and buy the right one.

I'm trying to, just looking at other options :)

Ahead of the fill valve is a push pin. Use a bent paperclip to push it in and then slide the floor plates off.

Swap floor plates and see if the mag fits.

Some of the retailers on here setup group buys with KWA USA so if that works you can just order that part for pennies and not get brunt on freight.

thanks will give it a go

bottom piece from mk23 too big oh well
the mag will lock in place without plate but takes more force than normal so don't think it's a good option anymore
don't have any gas handy atm to test either

i think i'll just buy an usp to match this mag, hahaha
