The Fort-20 is a 9×19mm polymer-frame handgun designed as a modern duty pistol platform. According to Fort, the pistol has been in production for roughly three years and is currently being manufactured primarily for Ukrainian military use.
Key features include:
• striker-fired operating system
• polymer frame
• ambidextrous frame-mounted manual safety
• tritium front and rear sights
• adjustable trigger with screws for pre-travel and over-travel
• optics-ready slide with modular mounting plates
• 16-round magazine
The pistol field strips in a simple manner similar to other modern service pistols and is designed to meet military durability standards.
Fort is a Ukrainian arms manufacturer that has historically produced pistols and rifles for Ukrainian law enforcement and military units. According to the company, the Fort-20 is currently in active service and being used by Ukrainian soldiers.
While production is currently focused on domestic military needs, Fort says the long-term goal is to expand exports to international markets.
