9MM Mak ammo is available in bulk for similar prices, or sometimes less than 9MM Luger ammo. It is also easily reloadable using Starline brass or by trimming 1MM off of readily available 9x19 (9MM Luger) brass. Mak sized bullets are also readily available from most reloading suppliers and bullet makers including inexpensive cast lead. So if you don't want to spend the $10/box of 50 for factory ammo, you can reload for it cheaply.
The Makarov is slim, and easily carried and the 9x18 round is a bit more powerful than .380. If fits in most common holsters designed for small semi-autos. Its all steel contruction, and weight make it easy to shoot well. It is simple and robust in construction, and is very accurate and reliable because of this fact.
I have four Maks. An EG, two Bulgarians and a Russian Commercial .380. I sometimes carry one of the Bulgies which I believe are the best value and still available for around $200 if you look. They are well worth that and more.
