TISAS 1911 Duty B45B | .45 ACP | 5″ | 10100502

The TISAS 1911 Duty B45B is a full-size, single-action 1911 chambered in .45 ACP built on a forged steel frame with the Ed Brown Bobtail cut. It features Novak-style front and rear sights, a skeletonized trigger, and black Sunburst G10 grips in a Cerakote finish. For a compact red-dot that pairs well for faster sight acquisition without exceeding $1,000, consider a Holosun 507K or a similar compact footprint optic (note: this slide is listed as not drilled and tapped, so professional fitting or an optic-specific slide plate may be required).

Real-world applications include concealed carry where the bobtail frame reduces printing, and precision range work or bullseye-style target shooting where the 1911 platform’s trigger characteristics are valued.

The finish and steel construction give it a durable, service-oriented feel suitable for regular range use and carry applications where a full-size 1911 is preferred.
