Cartridge ammunition 1 for a grenade pistol includes a casing 10 made, for example, of plastic, the casing having an opening. A projectile 11 is disposed in the casing opening and includes a tracer charge and/or delayed-action charge 11b. A primer 13 and a propelling charge 14 are disposed in a cup 12 at the base of casing 10. The cup 12 is composed of two mutually concentric sleeves 12a and 12b, with the inner sleeve 12b being mounted so as to be slidable in the outer sleeve 12a and extendable in the manner of a telescope. The outer sleeve 12a has a free end section which is provided with an external thread 100 followed by an annular, predetermined, circumferential break location 12d. The base of projectile 11 includes a sleeve 17 provided with an internal thread which can be screwed onto the outer sleeve 12a of cup 12. A firing channel 12c is provided in the bottom or end wall 12e of the cup-shaped inner sleeve 12b, with such firing channel being oriented toward the tracer and/or delayed-action charge 11b. The result of this construction is that the ammunition can be assembled easily, and an almost constant initial velocity can be maintained despite fluctuating environmental conditions.
