I have a Makarov 9mm high capacity I'm trying to identify. I bought it about 10 years ago. It has no importer stampings and no maker stampings. It serial number begins with a RT prefix. It's all black, no chrome or nickel. And what looks like aftermarket polymer grips. I would like to find out if it's a Russian Makarov or another countries manufacture. If anybody knows please let me know.
