I have lots of Glock 23 mags as I recently sold my Glock 23. I decided to try loading 9 mm in the .40 calibre mags. Exactly 14 rounds of 9 mm easily loaded in the mag. I went to the range with my G19 and decided to try it out to see how they worked. Wow, I was pleasantly surprised. They worked perfectly just like the G19 mags except I can legally shoot 14 rounds. I even tried shooting as fast as I could pull the trigger and no problem. Glad I kept the G23 mags.
