Gap-filler for Shield Arms Z9 Magazine and SS80/P80 PF9SS (Glock 43)

thingiverse

This gap-filler fills in the gap between the back end of the frame and the bottom-back end of the magazine to fit your hand more comfortably and in my opinion feels more stable than without. It also looks more aesthetically pleasing with the gap filled. Originally made for compatibility with the SS80, but fits the P80 PF9SS as well, but I'm not sure if this fits the actual original Glock 43. Just connect the gap-filler to the bottom end of the Shield Arms Z9 magazine with strong double-sided tape (normal scotch tape size) and you're good to go. - If you want a more permanent solution you can "crazy glue" the gap-filler to the metal part of the magazine only and not the thin polymer/plastic parts--this allows you to still remove the bottom plastic piece of the magazine
