Plus 9 aluminum glock magazine extension - Toni System Glock +9 Rounds Pad Magazine Extension

Great item, just wish it was made out of brass so it would be heavier. The only cosmetic flaw is that they don't cerakote the inside where the spring and bullets reside..... That doesn't make sense as you have raw exposed aluminum. Other than that great standard magazine extension with conventional magazine mounting extension. No removable lower floor plate like on a ZEV plus 5 magazine extension.
