PRODUCT DETAILS
TECH SPECS:
The FUSE by SIG SAUER blends full-size accuracy with micro-compact concealability. Its slim 1.1″ grip module and 21+1 capacity put unmatched firepower in a carryable footprint, while the 6 7/8″ optic-ready slide and 4.3″ carbon steel barrel deliver the range and control of a larger pistol. Comes factory-equipped with a Romeo-X red dot (SIG-LOC Compact) for fast, precise target acquisition. Includes two 21-round and one 17-round steel magazines, removable magwell, interchangeable backstraps, and a nickel-plated flat-faced trigger — everything you need for serious everyday carry.
The 4.3″ carbon steel barrel with a durable DLC finish increases velocity and optimizes terminal performance with modern defensive ammunition, while the 6 7/8″ optic-ready slide gives you a longer sight radius and the option for co-witnessed iron sights or a micro-red dot. SIG’s aggressive slide serrations and removable magwell improve speed and control, and the polymer LXG / Macro grip module offers a secure, comfortable purchase. The flat-faced trigger delivers a crisp pull and positive reset for reliable follow-up shots.
This model ships with a factory-installed Romeo-X red dot (SIG LOC Compact), providing a clear, fast aiming point out of the box. Whether you’re carrying daily or preparing for defensive scenarios, the FUSE gives you full-size power in a carryable, concealable package.
In the box: FUSE pistol (Romeo-X pre-installed), (2) 21-rd steel magazines, (1) 17-rd steel magazine, removable magwell, interchangeable backstraps, tool/keys as required, owner’s manual, and warranty documentation.

Ask a QuestionProven Arms & Outfitters A bolt-action rifle requires the shooter to manually operate a bolt to load a round, eject the spent casing, and chamber the next round. In contrast, a semi-automatic rifle is designed to automatically eject the spent casing and chamber a new round with each pull of the trigger. Semi-automatic rifles offer faster follow-up shots, while bolt-action rifles are typically more accurate due to their design.
