These grips fit the Taurus PT-1911. They are cut for the Taurus ambidextrous safety and larger Taurus grip screws. The grips you see in the photo are the ones you get.
These grips are made of an engineered hardwood laminate that is manufactured using phenolic resins in a heat and pressure process. The result is a material that is very hard and very dense but has the look and feel of wood.
