Can you remove the glass breaker on the end?

it looks to me like the glass breaker is part of the magazine cap and can most likely be replaced wit the magazine cap from the standard Duke model but I would contact Emperor firearms to be sure Sales: sales@emperorfirearms.com Dealers: dealer@emperorfir

Ben, it looks to be removable but I would confirm with Emperor Firearms Customer Service at (239) 561-3444 or by online inquiry here : emperorfirearms.com/contact-us.php
