The Boberg XR9-S was a semi-automatic bullpup handgun, designed and manufactured by Boberg Arms.

History

[edit]

In 2009, following a layoff from his previous employment, Arne Boberg founded Boberg Arms in Minnesota and was able to focus on the development of a pistol design, that he started in 2003.[3][4][5] Boberg's goal was to create a compact firearm without sacrificing power or reliability.[6] Among the early designs was the XR9, which remained a prototype and was never released commercially. The first production model, the XR9-S, where "S" stands for "Shorty", was a compact version of the XR9 design and was introduced in 2011.[5][7][8][9]

In November 2015, Boberg Arms was acquired by Bond Arms.[10][11] Following the acquisition, Bond Arms made a series of design improvements to the XR9-S and subsequently released the updated model as the BullPup9.[9][12]

Design

[edit]

The XR9-S is a semi-automatic pistol with a rotating-barrel, locked-breech mechanism using the short recoil method of operation.[2][13] It is chambered in 9x19mm Parabellum and is rated for use with +P ammunition.[2][13] Notably, the XR9-S employs a bullpup-style layout, uncommon in handguns, which accommodates a 3.35-inch barrel within an overall length of 5.1 inches.[2][14] To achieve this layout, the pistol utilizes a unique feeding system in which cartridges are extracted rearward from the magazine before being lifted and chambered during the forward motion of the slide after firing.[15][16] The XR9-S uses a double-action-only trigger.[2]

Variants

[edit]

Boberg Arms released two additional variants of the XR9-S. The XR9-L features a longer 4.2-inch barrel with an overall length of 5.95 inches,[4] while the XR45-S is chambered in .45 ACP with a barrel length of 3.75 inches.[17]
