The Taurus PT92 is a double action/single action, 9mm, double-stack magazine, semi-automatic pistol, manufactured by Taurus in the former Beretta factory. Like the Beretta, the Taurus PT92 utilizes the open-slide design where the upper portion of the slide is cut away exposing much of the barrel itself. The original PT92 was exactly like the original Beretta 92, though it was also unusual for the time in that it featured a squared trigger guard for supporting the index finger of the opposite hand while firing, a feature which was subsequently introduced to the Beretta 92 with the 92SB-F model in 1985. The Taurus PT92 is less expensive than the Beretta 92 in most cases. Taurus has begun manufacturing the PT92 with built-in accessory rails on the frame, a military upgrade of the Beretta 92F from which the PT92 is derived. While 15-round magazines were standard for the PT92 for many years, Taurus now manufactures 17 and 19-round magazines for the gun in order to give it comparable firepower to the Glock 17. This pistol is a licensed reproduction of the Beretta 92.
