The Tyrant CNC Magazine Extension for Glock 19 and Glock 23 in black (Tyrant CNC part no. TDG19MAGEXBLK) turns a 15-round factory magazine into a higher-capacity one without any tools. Tyrant says it adds 5 rounds of 9mm, or 4 rounds of .40, to the G19 and G23 magazine. It is machined from 6061 aerospace-grade aluminum and finished black, and a NoBak retention plunger lets it slide on and come off in seconds. A new power spring ships with it, so the longer magazine keeps feeding reliably. It suits competition and range shooters who want the extra rounds.
