The spring-loaded trigger guard is pivoted down and swung to either side on the frame, allowing removal of the slide. The 7 kg recoil spring wraps around and is guided by the barrel. The chrome-lined, four-groove, 9.27mm caliber barrel is pressed and pinned to the frame through a precision-machined ring. Other, more powerful cartridges have been used in blowback pistol designs, but the Makarov is widely regarded as particularly well balanced in its design elements. The PM is heavy for its size by modern US commercial handgun standards, largely because in a blowback pistol, the heavy slide provides greater inertia to delay opening of the breech until internal pressures have fallen to a safe level. The 9×18mm cartridge is a practical cartridge in blowback-operated pistols producing a respectable level of energy from a gun of moderate weight and size. Blowback designs are simple and more accurate than designs using a recoiling, tilting, or articulated barrel, but they are limited practically by the weight of the slide. In blowback designs, the only force holding the slide closed is that of the recoil spring upon firing, the barrel and slide do not have to unlock, as do locked-breech-design pistols. The PM is a medium-size, straight-blowback-action, all-steel construction, frame-fixed barrel handgun.

I was once asked about the Bulgarian Makarov.
Please note, the 1970 date is start of all Production at this plant using the 'Circle 10' code, the Makarov was first produced under Russian supervision in 1975, and first year of Production under Bulgarian control was 1976. The last four digits are the unit number in that production series.
