Glock .22 mag (18 round mod)

thingiverse

This will get Advantage arms glock kit mag to hold 18 rounds(only v1 is tested). The only issue is the follower will not lock the slide open when mag is empty. Lower spring guide adds 2. Follower adds 2 mag plate adds 4. V2 is same just made to fit Advantage arms mag better. I used a 0.04 feeler gauge to hold follower spring base in place as I slid mag base pad into place, a tap or two will get spring guide into place (you will need to break to remove). If you live in a (communist) state that has a limit of 10 rounds don't print this. this is for air soft...of course.... if it fits the real thing that is just a happy accident.....
