1 Simson- Suhl- Post unification Germany, widely regarded as best quality and fit and finish, excellent triggers, also the only Makarov that slide can be racked on when safety is on
2 East German, great quality aslo, pretty sought after, ive seen gunbroker prices anywhere from $325 to $450
3 Russian military spec- only came with fixed sights, good quaity guns but fit and finish is not as good as the Germans, but like all Maks great reliable gun. Pretty much on par with the Bulgariansexcept these are much more sought after by collectors since these were issued to the soviet military.
4 Bulgarian, quality about same as Russian miltary Mak except do not command the price of a russian due to them not being real collectors pieces, and these were made in Bulgaria till 99, theres a lot more of them out there. can find a good quality one for $200-$300
5 Russian Commercial Models- all have target adjustable sights and seem to be the least sought after due to the sights, theres got to be some other reason but im not sure exactly why.
So theres a little info man Im telling you to check out Makarov.com FAQs youll get all the info you need to make a good decision. Make yourself familiar with the markings and etchings so youre sure you know what youre getting and if youre just looking for a great shooter get a Bulgarian if you want collectible then thats up to you.
