Atiq Ahmad and Punjabi singer Siddhu Moosewala were both killed in public using illegal Zigana pistols. Manufactured by Turkish company TISAS, Zigana guns are banned in India but used by security companies, military units, and civilians in countries such as the US and the Philippines. Zigana pistols have a locked-slide short recoil operating mechanism with a modified browning-type locking system, feature an automatic firing pin block, and can hold 15 to 17 rounds., India News, Times Now
