MGC M59 modified for plastic cartridges?

Mentioned in another thread - an MGC M59 with exchangeable detonator pins that allow using open cartridges (original design), CP-HW ones (later improvement) as well as the latest cartridges made for Tanio Koba GM7 (cheap and plentiful).

Corrections, comments and translation are welcome!

EDIT: changed thread title from "MGC M59 modified for Tanio Koba GM7 cartridges", as it is obviously wrong.

I am a bit confused are you saying that the GM7 45rounds will fit! i have a M59 and the rounds are small ingram size rounds how do you get a 45 round to fit and is the GM7 det pin or special made. if i can get GM7 rounds into mine brill as i have a ton of rounds for it.

Duh!!!

I completely suggested myself by looking at the box with seemingly plastic cartridges that looked for me just like GM7 ones.
Also detonator pin (the one with a rubber) seemed similar.

Of course M59/39 uses 9mm cartridges, while GM7 is a 1911 and uses .45, so this is a very incorrect information.

Explanation might be in text written on pictures, translation should solve this.

PS: I will change thread title.

Looking at the pics its an easy mistake to make as the plastic rounds look more 9mm than 45, its either a comparison of opend style rounds or they have 9mm plastic rounds out (wishfull thinking).
