The Makarov (9x18) design is a simple straight blow-back operation and very rugged. It only has 27 total parts. They are known to be one of the most reliable semi-auto pistols ever made. The East German (Ernst Thaelman factory) versions of the Makarov are generally considered to be the best of the Makarov's. At that price its a steal. Very good condition EG Maks are now going for $400+. Russian, Bulgarian and Chinese Makarovs are also relatively common and also typically well made but East German guns are generally superior in fit and finish.
