Who makes these grips?

[Blackhawk]

Looking for replacement grips for my 1911. I am wanting to switch from current double diamond checkered set up to ones I have seen described as tactical or ranger styled grips ( i.e. grips are 1/2 smooth and 1/2 checkered ) . Which manufactureres make these grips?
