The KRISS® MagEx2 consists of an inner and outer extension sleeve, made of advanced polymer composites, along with an extended spring. When combined with a factory standard Glock® magazine body and follower, the MagEx2 adds 23 rounds to the capacity of a G17 magazine, for a total of 40 rounds of 9mm; and it adds 18 rounds to the capacity of a G20 magazine, for a total of 33 rounds of 10mm.
The KRISS® MagEx2 is designed to extend the capacity of a standard magazine for use in the KRISS® Vector 9mm and 10mm models. However, it is also compatible in other firearms designed to use Glock® 9mm and 10mm magazines, including Glock® pistols, pistol caliber carbines, and magazine well conversion kits for AR-15 PCC conversions.
