Here's my modified XL (XXL?) Nill grip for the MR73. I asked for it to be roundbutted, for the checkering above the thumbrest to be removed, for the finger grooves to be removed, and for some Manurhin medallions I bought off eBay to be installed.
Before on the left, after on the right:
It fits my hand better now, and is a lot more comfortable. (Note how my middle finger now covers the grip screw completely.
I expected the roundbutting to be more aggressive, but I gotta admit it feels really good, really stable, as is.
