Widely regarded as the first commercially successful automatic handgun, the TBG-12 was not designed nor used by or for any military. Chambered in 10.2mm Rimmed, the TBG-12 was known to have an extremely snappy recoil pattern and a heavy pushback due to the bolt reciprocating and lack of a proper recoil spring. The TBG-12 was also one of the first direct blowback striker fired pistols, with the striker pin located inside the semi hollowed out bolt, both encapsulated by the recoil spring. The rear of the bolt was exposed, and a vertical piece was attached to add purchase, as it functioned as the charging handle. The takedown screw was attached directly to the bolt and it protruded out the top of the gun, reciprocating with the bolt. This screw was the only thing retaining the bolt, which forced designers to reduced the strength of the spring. Removal of this screw allowed for the bolt to be removed. The stamped sheet metal magazine was notoriously fragile, breaking easily, but it rarely jostled in the magwell and reliable fed rounds into the chamber. The grip was interchangeable, only using two bolts to secure it to the receiver body. A rear sight notch is carved into the charging handle and the takedown screw, reducing overall accuracy. ----------------- Action: Closed Bolt, Direct Blowback Caliber: 10.2mm Rimmed Capacity: 7+1 (Stick Magazine)
Made in Keynote as per usual! Click for next photo 10.2mm Rimmed: Derived from the older 10.8mm Beryl (a lightweight rimfire cartridge designed for revolvers), the 10.2 Rimmed essential functioned as a companion cartridge, smaller and more compact while still retaining the stopping power of a Beryl. Any weapon that could feed Beryl rounds could take 10.2mm ammunition, instantly making it extremely popular. One of the weaknesses of Beryl derived calibers was that due to the shape and size of the primer, automatics of the time were unable to cycle the round properly, leading to it’s modern reputation of an unreliable round.
