Custom Handguns are factory pistols modified to individual specifications, typically starting with platforms like the 1911, Glock, or Sig Sauer. Aesthetic options include engraved slides, custom finishes, and exotic wood or G10 grips. Performance modifications include match-grade barrels, tuned triggers, ported barrels, compensators, fiber optic or night sights, and enhanced magazine wells. Tactical builds often add optics-ready slides and accessory rails. Work is done by gunsmiths or custom shops, and results vary from competition-oriented builds to personal-defense setups to collector pieces.
