Makarovs are a very basic, solid, accurate pistol. Have been around since the early 1950's and were primarily used by Russian Military and Police until 1991.
MAKs rep has always been for simplicity (about 20+ parts), accuracy and their durability.
Was able to buy one a couple weeks ago for about $300... it was in VG+ condition, had some holster wear but never really shot much.
Took it to the range last week (along with my CZ-82)... and love it! Flawless, very accurate shoot. Actually has a 'slimmer' feel compared to the CZ.
Agree with BigJim... unless you really consider this a 'must have' pistol and it's in like-new condition, I doubt I'd spend $400 for one!!
Supposedly, the East German and Bulgarian Maks are the one's to buy. Keep lookin' around, they usually turn up in the $300 range.
They ARE nice, sweet little pistols and could be a good CCW pistol!!
