Full-size capability and micro-compact concealment combine with the all-new FUSE from SIG SAUER. Its 21+1 capacity meets a razor-thin 1” wide grip module for unmatched versatility and shootability. FUSE delivers the accuracy and grit of a full-size pistol with its 6 7/8” optic-ready slide, longer than any compact in its class for improved sight radius and enhanced control. Equipped with a fiber optic front sight and a 4.3” barrel, FUSE provides improved ballistic performance from today’s defensive ammunition for faster velocities and maximum expansion on target.

All the benefits of a full-size pistol fused with the concealability of a compact. Built from the roots of the P365, a true crossover carry has arrived.
