As materials technologies continued to develop, it became possible to produce a ceramic-metal composite pistol. The advantage of this technology was that it allowed the development of weapons that could not corrode, and were lighter than their traditional counterparts, but had all the strength of steel. The first service weapon built with this technology was the LP-09 (LP in this case being for Lightweight Pistol, though later LP-09 Pistol 4Cdirected energy pistols carried the designation LP for Laser Pistol). Firing a heavy armor-piercing 12.7mm CAP (.50CAP, Composite Automatic Pistol) round, and employing an internal hammerless action and an advanced roller-mounted barrel and delayed blowback slide for excellent recoil compensation, this weapon was immediately acquired by all branches of the Southern Cross, with the GMP’s Enforcement Corps and the TASC being the biggest adopters.

Though the M-37 Weasel and the M-35 Ferret continued to be used, having already been purchased in large numbers, the all-weather nature of the LP-09 caused further orders of these previous pistols to have been cancelled by 2027. By the beginning of the Second Robotech War, the LP-09 was well on its way to becoming the standard field sidearm of most branches of the military. The LP-09 was generally reliable, though some of the early models were machined improperly, leading to a slide that would jam shut. This problem was the only blight on an otherwise fine gun.
