TISAS 10100533 1911 Duty SS45R .45 ACP 5″ Stainless

The TISAS 10100533 (SS45R) Duty is a full-size 1911-pattern semi-automatic pistol chambered in .45 ACP. It pairs a 5-inch barrel with a stainless finish, extended beavertail grip safety, and an ambidextrous extended thumb safety to suit shooters seeking traditional 1911 ergonomics with modern refinements. For a compact reflex optic under $1000 that pairs well with this platform, consider a Holosun 507K for a low-profile red dot option that preserves slide holstability while improving sight acquisition.
