BP-30
The BP-30, officially known in Umardi as باتگانور تپانچه (ˈÆnglish: Battganuur Pistol), is a Battganuuri semi-automatic pistol. Development for the BP-30 began in 1928, when Mazra Adal took inspiration from the Keun series of pistols, reducing the number of parts and details in order to simplify manufacture, and essentially create a cheaper alternative for Battganuur, during a time when the state relied almost entirely on Burgoignesc weapons. Battganuur ceased production of the BP-30 in 1954, but it is still used internationally, particularly by the Calderan Republic.

Development
In 1928, the Battganuuri Chief of Ministers ordered the military to begin the process of adopting a new handgun which could be produced locally and at cheaper cost than the colonial era Burgoignesc handguns used by the military at the time. The military began examining various candidates to either design an entirely new handgun, or present a better previously designed handgun. After witnessing the success of the expensive Keun M1922 and Tauk Modell P at otherwise lackluster trials, Mazra Adal presented design documents for a new, incredibly cheaper but still promising design inspired by these handguns. Authorized to begin manufacture, on 7 January 1930, the Battganuuri Military recognized this new handgun as excelling over others in both reliability and cost, so in a few weeks, 1,000 copies were ordered for troop trials, and the handgun was formally adopted for service.
The handgun was widely used during the Second Great War on the Audonian Front, being utilized by both "princely offensive" anti-Burgoignesc forces and pro-Burgoignesc forces from Battganuur and Bulkh. This resulted in minor changes for ease of manufacturing, including changes to the barrel, disconnector, trigger and frame, the most notable ones being the omission of the removable hammer assembly and changes to the full-circumference locking lugs. This wartime variant of the BP-30 was dubbed the BP-35, given it began production in the beginning of 1935. The BP-35 was notably not as liked as its earlier design, and thus it ceased production at the end of the war in 1943, with only 93,000 being produced.
Design details
Externally, the BP-30 is very similar to Tauk's blowback operated Modell M semi-automatic pistol, and internally it uses Tauk's short recoil tilting-barrel system from the Modell P pistol. However, it employs a much simpler hammer/sear assembly than the Modell P. This assembly is removable from the pistol as a modular unit and includes machined magazine feed lips, preventing misfeeds when a damaged magazine is loaded into the magazine well. Battganuuri engineers made several alterations to make the mechanism easier to produce and maintain, most notably the simplifications of the barrel's locking lugs, allowing fewer machining steps. Some models use a captive recoil spring secured to the guide rod, which depends on the barrel bushing to hold it under tension.
The BP-30 is chambered for the 7.62×25mm Battganuuri cartridge, which was itself based on the similar 7.63×25mm Lachsen cartridge used in the Lachsen C96 pistol. The 7.62×25mm cartridge is powerful, has an extremely flat trajectory, and is capable of penetrating thick clothing and soft body armor.
