Video | What’s Included | Specs | Pictures | Restrictions
Whether you’re competing and need the advantage of additional capacity or you just want a few extra rounds in your spare carry mag, baseplates are a great way to extend your standard capacity magazines. The Henning Group Mag Extension comes with an extended spring to ensure reliability and extend Glock 17 mags to a maximum of 23 rounds, though we recommend loading them to 22 for consistency. When paired with an OEM Glock 17 Magazine, these mag extensions are USPSA Legal for Carry Optics, Limited Optics, Limited, and Open.
