The VIS 100[1][2] (formerly called PR-15 Ragun) is a semi-automatic pistol developed and manufactured by FB "Łucznik" Radom for military and law enforcement personnel.

The project's head designer was Piotr Dygas, who was supported by an engineering team which included Paweł Madej and Marian Gryszkiewicz.

Despite external similarities to the MAG-98, the PR-15 was actually designed from scratch because FB Radom did not have the technical documentation of the pistol, which was owned by a different company that was bought by Works 11.

[11] The VIS 100 is a semi-automatic pistol chambered for the 9×19mm Parabellum round, utilizing the short recoil method of operation.

[12] It features an aluminium-alloy frame with a MIL-STD-1913 compatible rail, which enables the attachment of tactical lights or laser sighting equipment.

It was developed to be fully ambidextrous, with the magazine release, slide stop and decocker lever positioned on both sides of the gun.
