Esstac double pistol KYWI pouch, works well with the newer Glock 24 round 9mm and 22 round 40cal magazines and +5/6 round extensions for FULL sized glock mags. Glock +2 extension work but not ideal due to the limited length stickout out. Not ideal for standard G17 mags with no extension and Glock 19 mags are to short no matter the extension. Midlength allows for 1inch lower placement on a belt, allowing for easier manipulation and less interference with armor. There are 4 rows of webbing on the back of the pouch. You only use the Top 3 rows of webbing when mounting (not 4).
