⚠ ▼ Verify Gen 1–4 Fitment

Gen 1–4 parts are not automatically compatible with Gen 5, Gen 6, or slimline Glock models like the 43, 43X, or 48. Verify your model, generation, caliber, frame size, slide length, and fitment notes before ordering.

  • Check model, generation, and caliber.
  • Confirm Gen 1–3, Gen 4, or Gen 1–4 compatibility.
  • Read all product fitment notes.
  • Verify first. Guessing builds parts-bin funerals.
