The Tisas 1911 Duty (brand part no. 10100528AA5) is a full-size .45 ACP 1911 built with a stainless steel slide and frame, a 5-inch barrel, and a Picatinny accessory rail for a light or laser. Tisas gives this exclusive Duty configuration an 8+1 capacity, one round over the classic government-model count, in a corrosion-resistant all-stainless build that holds up to daily carry and steady range time.
