This grenade consists of a bell-shaped body of thin steel with a slightly convex aluminum closing disc, a graze fuze which screws into a cylindrical projection welded to the base of the body, and a finned tail unit. The bursting charge of cyclonite wax is cast around an aluminum hollow charge liner which is hemispherical in shape. A detonator and intermediary exploder are contained in an aluminum magazine which fits into the base of the main explosive cavity. The tail unit screws onto the base of the fuze housing and consists of a drawn-steel tube with six vanes formed in pairs. The cartridge is of the 7.92 mm small arm type with an undyed hollow wooden bullet.

This grenade, while larger and of slightly different contour than that described on the preceding page, is basically the same in construction and operation. The body of pressed steel contains a steel cone around which the T.N.T. filler is cast, and at the bottom of the filler is an exploder pellet of penthrite wax. Two types of stem may be used, one entirely of light alloy and the other of plastic with a steel shank by which it is screwed onto the body. The booster assembly and the percussion type fuze are both located in the stem divided by a perforated septum which contains a small flash pellet. At the base of the stem is a rifled band which corresponds to the rifling on the discharger. The assembly is closed by a base plug.
| Overall length | 7 ins. | |
| Maximum diameter | 1 3/4 ins. | |
| Color | Black overall | |
| Total weight | 13 1/2 ozs. | |
| Weight of filler | 4 1/2 ozs. | |
| Filler | T.N.T./Cyclonite | |
| Range (maximum) | 100 yds. |

The Gewehr Panzergranate is constructed in two parts, the head and the stem. The head, a seamless steel tube fitted with a light ballistic cap, contains a hollow charge cone and an explosive filling of T.N.T. A cavity is provided in the rear portion of the main filling to take an exploder of penthrite wax. The stem of light alloy or aluminum is screwed onto the head of the grenade. It is divided into two compartments. The upper portion contains the booster which consists of a detonator surrounded by a penthrite wax filling contained in a light alloy case. The percussion type fuze is located in the lower part of the stem. In the septum is a small flash pellet held in place by a perforated screw plug. A pre-engraved driving band is formed on the outside of the grenade approximately 1/4 inch fromn the base. The entire assembly is closed by a base plug which positions the fuze by a stem which fits into a recess in the rear of the striker body.
| Overall length | 6.4 ins. | |
