Boberg XR9S & XR45S: The Bullpup Pistols

Published on February 12, 2019
Duration: 13:31

The Boberg XR9-S and XR45-S are unique bullpup pistols designed by Arne Boberg, maximizing barrel length in a compact frame through an innovative rearward feeding mechanism. This design places the chamber above the magazine, allowing for a longer barrel than traditional pistols of similar size. While offering a compact footprint, they feature a Double Action Only (DAO) operation and a rotating barrel locking system. The pistols are known to be sensitive to ammunition quality due to their unique feeding cycle, which can lead to jams with poorly crimped rounds. Boberg Arms was acquired by Bond Arms, with original Boberg pistols now considered collector's items.
