I believe he can reverse the pattern though I didn't order any that way for my first lot.
I can order them if you like.
A simple 60 grit sandpaper does the trick nicely.
Afterward wipe down with a rem-oil type product to get rid of sanded fibers and restore to a true black appearance.
This pic should give you a good idea though the flash makes them look shiny and they are more of a matt finish:
The process took me less than 10 minutes. I think the advantage is the truly custom level texture but if you would like I'm glad to sand them to my preferences pre-shipping.
I send sanding instructions in the package.
They are "standard" rather than "slim-line" grips; we are currently testing a thin/"slim-line" grip for those interested.
(I will measure them next time I get to the shop.)
They are slightly thicker than the grips that come on most 1911s quite a bit thicker than the grips that come on the PT1911.
I have only posted them on ebay. Anyone who would like to circumvent the ebay process can email me at firstname.lastname@example.org
