Even earlier editions of D&D are better suited to low-magic. You stop acquiring hit dice after levels 9 or 10, attack and AC are hard capped at +20 and AC 30 (adapted to the equivalent of 3e) so the best fighter will always have a 55% chance to hit the best defended monster, few monsters (giants, dragons, and some extraplanar creatures) have HD above 9, and the only time you need to worry about magic items are weapons as some editions have monsters immunity.

Go grab Swords & Wizardry, OSRIC, Labyrinth Lord, Dark Dungeons, or Lamentation of the Flame Princess, all of which are free.
