I have settled on Herrett's grips for my M63. I have rubber Pachmayer grips, a Tyler T used with the stock factory grip and the Herrett grips. The rubber Pachmayer is bulbous and heavy. The Tyler T is a huge improvement over the stock factory grip but still seems a bit small. The Herrett grip fills the hand while remaining trim and looks good on the gun. The Herrett is a tad shorter than Hunts22's Hogue. The Hogue uses that stirrup attachment which adds length.

My only complaint with the M63 is the front sight. The front sight is too thick and the red ramp insert isn't good with my eyes. I really dislike that glowing blob of plastic. A black .100" thick Patridge front sight would be killer on a M63. Someone on this forum has a 63 set up like that and I'm jealous every time they post a picture of it.

Every normal man must be tempted, at times, to spit on his hands, hoist the black flag, and begin slitting throats.
