"иррши"
Well, this is an interesting thread..... I got on an online Russian keyboard and typed in the above. That's what it looked like to me anyway. Then I choose a google translator. The answer came up " tajik" in English Then I looked up "tajik" and found that it is an ethnic group in the country of, and around,...........Tajikstan.............a country to the NE of Afghanistan, very mountainous and rugged.
Of course, I made a two assumptions here.1. That the word is Russian 2. That I identified the characters correctly. But, that gun looks like it would be used in that region doesn't it?
P.S. this is what retirement allows me to do, l.o.l
