The LP-42 Flare Gun, also known as Leuchtpistole 42, was a WW2-era German flare gun. Using a simplified design compared to the Leuchtpistole to save precious war materials and production effort, the LP-42 is made out of stamped galvanized steel rather than being fully machined. The LP-42 is capable of firing 27mm flares, smoke grenades, anti-personnel grenades, and anti-armor grenades.
Some LP-42s have rifled barrels, much like the Kampfpistole, but these examples are very rare.
