This is another of the non-lethal Russian pistols for self defence. The 13mm UDAR fires a pepper spray load causing severe irritation. Translated from available Russian internet resources this cartridge is called the The BAM “Black Widow”. It contains 1% OC (selective concentrate of red pepper). The initial OC, in this case, is a crystalline white powder consisting of 96-98% of a mixture of capsaicinoids, mainly capsaicin (about 70%) and dihydrocapsaicin (about 26%).
