The Tyrant CNC Magazine Extension in gray (brand part no. TDG48MAGEXG) adds four rounds to a Glock 43X/48 factory magazine. Tyrant CNC machines it from aerospace-grade aluminum in the USA and ships it with a 10 percent power spring. A retention plunger lets the extension slide onto the bottom of the magazine, so installation takes about ten seconds with no tools. It gives slim-frame carry pistols more capacity without changing the grip you already know.
