The Mars Automatic Pistol, developed by Gabbett-Fairfax, was historically the most powerful self-loading pistol for a period. It features a heavy 3 lbs 5 oz build and a unique single-action-only mechanism with a four-lug rotating bolt. Its unconventional feeding system extracts cartridges rearward from the magazine before chambering, aided by a disconnector that delays bolt closure for improved reliability.
The 1896 Maxim-Silverman .455 Webley pistol, a rare collaboration between Hiram Maxim and Louis Silverman, is a massive 3.6 lb firearm with unique ergonomics like a central rear sight. Its simple 17-part blowback design was efficient for its era but ultimately flawed due to an overpowered .455 caliber and ammunition compatibility issues, likely leading to Hiram Maxim's disinterest.
This YouTube video from TheFirearmBlog reviews the Boberg XR9-L, a compact carry pistol noted for its unique feeding mechanism. Unlike conventional pistols that push cartridges forward from the magazine, the Boberg feeds them backward, a design inspired by the Mars Automatic Pistol. This innovation aims to achieve a longer barrel within a compact frame. The description highlights that while truly novel firearm designs are rare today, creative combinations of existing elements lead to more efficient and reliable firearms, with the Boberg XR9-L serving as a prime example.
