The Sig Sauer P365-Fuse pistol (brand part no. W365F-9-BXR3P-RXX) is a First Responder Firearm restricted to purchase by verified first responders under Sig Sauer’s program rules, not a standard retail item available to the general public. Sig Sauer built the Fuse to combine full-size capability with micro-compact concealment, packing a 21+1 capacity into a razor-thin 1-inch-wide grip module. The 6.875-inch optic-ready slide comes with a Romeo X Compact circle-dot optic mounted, longer than any compact in its class for improved sight radius and control, and a 4.3-inch barrel paired with X-RAY3 sights delivers improved ballistic performance from modern defensive ammunition. Among First Responder-exclusive semi-auto handguns, this P365-Fuse is available only to eligible first responders.
