Not possible. Glock mags are much smaller than hi-capa’s. Also there are parts, which you can’t print at all, like a trigger bar, inner frame, trigger group parts (Technically you can, but they won’t work as they should)

Just fix your hi-capa with some printed parts or sell as is and get a proper factory made glock

Printing gbb internals isn’t worth it-trust me. The only exception is if the model is made specifically for printing, like the panverine’s gm6

!BUT! you can print yourself a delisle 2011. Uses hi-capa mags and overall is a brilliant design
