In CS 1.6, the fragmentation grenade, like all the others, was round and elongated. In CSS, the same green flop from reality, and specifically the American M26, which did not look very good. Therefore, I replaced the fragmentary one with one such as a flash drive and a smoke one, made on the basis of a flash drive.

Once I already made a MAC-10 with a muffler from TMP.
I came up with the idea to do the same thing only with the MP5, but with a silencer from the M4A1. A little illogical, because in reality the MP5 uses a 9mm silencer, and the M4A1 is NATO.
Uses MP5-SD audio from CS: GO.

It works on the 34th version. The author is unknown.
