Tisas USA, and an SDS Arms brand, is building upon their release of the 1911 Duty and Carry models for 2025. A 4.25” (Carry) and 5” (Duty) hammer forged barrels are still standard, but new for this year on the Tisas 1911 Duty and Carry models is a 193 Picatinny Rail, an extended slide stop and 1/3 fiber optic front sight (co-witness).
