The E-11 blaster pistol represents a weapon class that saw action during the era of the Old Republic. Zeerid Korr, a Human, occasionally carried an E-11 blaster pistol concealed beneath his jacket in a single-sling holster, opting for this blaster instead of his usual dual GH-44 blasters.
The E-11 blaster pistol made an appearance within the pages of The Old Republic: Deceived, a novel penned by Paul S. Kemp and released to the public in 2011.
