After trying to dig deeper online, I can't say the translation of the marking is "tajik", I think the translator detected the Tajik language, which uses a form of cyrillic, Russian. So I say this markng has to do with Tajikistan, but not sure of its literal translation. Well, that's my input on the topic, if anyone remembers what it was."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
