Designed for shooters who need higher capacity without sacrificing reliability, this kit is popular for range work, competition, and backcountry applications where 10mm firepower matters. Each extension maintains the magazine's feed geometry to preserve function with factory and aftermarket ammunition.\u003c\/p\u003e\u003cp\u003eMachined from reinforced polymer with a matte black finish, the MagEx2 installs without permanent modification to your existing magazines. Installation requires disassembly of the factory magazine baseplate and spring, replacement with the included MagEx2 extension tube and spring, then reassembly—basic gunsmithing skills and proper magazine disassembly tools are recommended. This 3-pack includes everything needed to convert three magazines: extension bodies, springs, and baseplates.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Magazine Extension Kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearms:\u003c\/strong\u003e Glock 20 (10mm Auto)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCapacity Increase:\u003c\/strong\u003e +18 rounds (converts 15rd to 33rd)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Reinforced Polymer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Matte Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Moderate difficulty, magazine disassembly required\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e 3 extension bodies, 3 springs, 3 baseplates\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KRISS USA, Inc","offers":[{"title":"Default Title","offer_id":47943824212223,"sku":"KRKVA-MX2K10BL01","price":85.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/2142688.jpg?v=1766602431","url":"https:\/\/doublestackstore.com\/products\/kriss-magex2-kit-for-g20-18rd-3pk","provider":"Double Stack Store","version":"1.0","type":"link"}
