After 1928 the application of the essentially new-fangled Gyrojet cartridge technology having been proven to be successful Webley deemed it necessary to try and utilize their original .455 pistol cartridge. Due to the round being designed for a heavy-framed revolver, they deemed it necessary to gain the assistance of George Gibbs, who offered his phenomenal insight into large-bore semi-automatic armaments. As such, development sped along at a startling speed. In fact, the mechanism for the Webley-Gibbs MKII 1930 Repeating Sidearm is a scaled down version of the Enfield-Gibbs MKIII 1927 Repeating Gyro Rifle's mechanism.
This model may use a different bolt and altered frame, but it loads it's .455 Webley-Gyro JSP cartridges via stripper clip. In order to load the operator must toss the weapon into his left hand and proceed to push the burnished tab sticking out from under the barrel, this activates a miniaturized hydraulic shunt, and thusly opening the mechanism. The user must proceed to take a stripper clip and insert it into the opened mechanism, upon doing so the user must push the rounds into the mechanism, thusly feeding them into the eight round internal magazine. After loading the ammunition, the soldier need only tug the mechanism and it will smack forward, not just chambering a round but priming the mechanism for further firing. This allows for quick reloading, and a very stable and rugged receiver frame.
Many soldiers have taken to keeping multiple of these four pound pistols tucked into the their webbing, whether it be via multiple holsters or friction. If anything, some British troops have made claims of feeling "Piratical" whilst using it. In fact, the Royal Navy's boarding crews and the Royal Marines have gone so far as to call it the "Drake" after Sir Francis Drake due to it's likeness to something a member of his crew would use.
