H&K G 11 designed 1990 with self combustible cartridge cases

 

Thrown out because of reunification costs.

 

The pistoI grip is ideally placed very close to the center of gravity of the weapon which reduces the weight that would be placed on the supporting arm holding the front of the weapon. This then guarantees quick readiness to shoot in any position. The trigger group contains the trigger mechanism, the safety mechanism, and the selective fire indicator that can be switched from safe to single shot to three round burst to fully automatic. The burst mechanism fires at greater than 2000 rounds per minute, and the normal automatic rate of fire is approximately 600 rounds per minute.

The magazine positioned parallel to the bore axis above the handguard is taken out toward the muzzle for reloading. It is spring driven, single-stacked and holds 50 cartridges. The approximate number of cartridges is visible from the outside even when the weapon is ready to fire. The magazine can be manually reloaded with individual cartridges or directly from the packing unit, which can be used as a loading device.

I think is  streets ahead of the HK 7 . But I do have a warm feeling for the trapdoor Springfield

Contrary to the round cartridge cases, the geometry of the propellant body is rectangular so that wasted space which was previously unavoidable when the cartridges were placed in magazines or packages has been eliminated. Moreover, the friction which exists in conventional magazines between the individual cartridges and the walls of the magazine no longer exists. It is not uncommon for this friction to be the main cause of malfunctions in conventional weapons.

The smaller dimensions of the cartridge ensure reduced packing volume and high magazine capacity. The elimination of the case reduces the cartridge weight considerably. The high rate of fire is possible in the 3-round burst due to the combination of a short cartridge and a minimal feed distance.
