KWA M1911 MK 21 round Mags?
 

Does anyone know where these can be purchased? I only found one site, which is on pre-order, but there is no order button :(

Can't even find the old 14 round ones either T___T In desperate need for some as I only have one

These mags are brand new and even the old ones are massively under produced (probably because they realized people wanted more rounds so skipped to higher round magazine production)
