I don't know about Hugh's opinion, but while we are waiting for it, let me add mine.

Pressed checkering, such as that found on older Remington and Winchester rifles, causes the pattern to be pressed into the wood, not outward...

The result is more like diamond shaped holes...which form the pattern.

Pressing checkering on curved surfaces like Luger grips, would be a risky proposition which would likely result in a lot of cracking during the manufacturing process... I think it is highly unlikely that Luger grips used pressed checkering.

I have never seen an original Luger with wood grips that looked like it had anything but cut checkering... which results in diamond shaped bumps instead of holes...much better for a gripping surface.
