Telltrig-7 blaster

The Telltrig balster pistol was a holdout blaster, ideal for use in confined spaces. One variant of the blaster was the Telltrig-7. Han Solo was known to hide a Telltrig-7 in a rag for use when he was repairing the Millenium Falcon, and could not draw his DL-44 blaster without drawing attention.
