The SD configuration encloses the Compact suppressor within the dedicated SD handguard, creating a true integrally suppressed .45 ACP package. The 5.75 in barrel and enclosed can keep overall length manageable while maintaining a streamlined profile.
Its operating system is closed-bolt blowback with a B&T hydraulic buffer, a setup known for consistent cycling in .45 ACP. Controls include a safety selector and forward, ambidextrous charging handles for bilateral operation.
A full-length Picatinny top rail runs the receiver for mounting sights or accessories, complemented by a 6 o'clock rail segment. Factory flip-up front and rear iron sights are installed. The telescopic two-rod stock provides a compact, adjustable shoulder interface.
Construction pairs an alloy receiver with polymer frame components. Markings include the Swiss cross emblem and B&T USA, Tampa, FL import stamp, reflecting Swiss manufacture and U.S. import. Capacity is 30+1 rounds using the included factory steel magazine. This package transfers as two NFA items (host and suppressor) and will require the processing of both.
