The ULP-4 was a Laser Pistol developed by Ultor in an alternate timeline where Ultor ruled Earth. During the first two Saints-Ultor Wars it was the most common sidearm used by Ultor SWAT, and Masako teams though both the URP-5 Rail Pistol and the older ULP-3 were still in use, and many stolen or captured Ultor weapons were used by various resistance forces fighting Ultor's control. The weapon fires a single laser bolt with each trigger pull and requires 0.2 seconds to cool between shots.
