Original Item: Only One Available. This is a totally inert BATF approved example of the Soviet F1 Grenade offered in very good condition. The Russian F1 hand grenade is an anti-personnel fragmentation defensive grenade. It is based on the French F1 grenade and contains a 60-gram explosive charge (TNT). The total weight of the grenade with the fuze is about 600 grams.

Due to its shape, it is nicknamed the limonka (fem. "lemon"). It is also nicknamed Efka (Russian: Эфка) for the letter F. It is similar to the American Mk2 grenade "Pineapple grenade", which was also ultimately modeled on the French F1.

This example is missing all of the paint, and looks like a typical "battlefield pickup" example. It was most likely recovered post war, never having been used, and then was deactivated. The fuze still has the correct spoon and pull pin, and can unscrew from the grenade housing for inspection of the interior.

A really nice example of a Soviet F1 grenade, ready to display!

Fuze
The UZRGM (Universal'nyi Zapal, Ruchnaya Granata, Modernizirovannyi > “Universal Igniter, Hand Grenade, Improved") fuze is a universal Russian type also used in the RG-41, RG-42, RGO-78, RGN-86 and RGD-5 grenades. The standard time delay for this fuze is 3.5 to 4 seconds. However, UZRGM fuze variants are available which give delays between zero (i.e., instantaneous, specifically for use in booby-traps) and 13 seconds. It is possible to hear a loud "pop" as the fuze ignites and begins to burn.

History
The F1 was introduced during World War II and subsequently redesigned post-war. It has a steel exterior that is notched to facilitate fragmentation upon detonation and to prevent hands from slipping. The distance the grenade can be thrown is estimated at 30–45 meters. The radius of the shrapnel dispersion is up to 200 meters (effective radius is about 30 meters, by some sources (Russian)). Hence, the grenade has to be deployed from a defensive position to avoid harm. About 60 percent of the grenade body pulverizes during the explosion, only 30 percent of the body splints into 290 high velocity sharp cut splinters each weighing around 1 gram with initial speed of about 700 meters per second.
