The Makarov is a good pistol for what it is supposed to be.
It is small and light and reasonably accurate and although the west goes on about how it is weaker than the 9mm German round, with full metal jacket ammo they both essentially make the same diameter hole in the target.
The only effective pistol calibre weapons are submachine guns which are lethal because of the number of holes you end up bleeding out of.
Pretty much all structures in Russia used the Makarov, but there have been a lot of attempts to replace it.
The SR-1 Gurza pistol in 9x21mm was probably the first pistol to replace the Makarov but it was only used by special forces because the ammo was not mass produced at that time. The PYa Yargan pistol seems to be the pistol they issue to troops equipped with Ratnik, but there are a couple of new pistols that have also been shown that the makers claim are going to replace the Makarov.
The problem there is that they are all right because no matter who their new pistol is for the existing pistol will be the Makarov, so when the makers of the Boa Constrictor say the interior ministry is adopting their pistol to replace the Makarov then they are not wrong.
The trick of course is to find the pistol and pistol maker that has signed a contract with the Russian Army to replace the Makarov as a general squad issue side arm... they are all also making updated models of their pistols too.
