While I can't offer an opinion on the newest model of Sig's P226, I can say that the one I've been shooting for the last few years has been flawless. It has over 12,000 rounds through it and has proven to be very accurate as well as reliable. It has a pair of Piranha Hogue G10s grips that I find very comfortable and provide a good grip. One thing about the G10s, any of the textured grips (meaning checkered, chainlink or piranha) can be tuned to provide the grips texture you prefer, to a point, if you find them to be a little too aggressive. When new, fresh from the machines, the little points of the textured surface can feel a little sharp but a couple of swipes with a very fine sandpaper knocks the tips off and tones down the grip. Continue taking light passes with the sandpaper until you get the feel you want. None of this will affect the color of the textured area since the color is impregnated throughout the grip. I do not touch the smooth portions of the grip to avoid any scratches that could show.
Hope this helps...Sig Marine
