Hello, I'm looking to buy a makarov, i'd like it in russian however im having a hard time finding it in 9x18Makarov I see them everywhere in .380 how hard is it to convert? i've heard it's just a simple barrel change but i don't want to buy into a 380 only to find out I cannot convert it, and it's not a job for a newbie to gunsmithing if anyone can recommend me a gunsmith i'd really appreciate it!
