As for the slipperiness of the P-07 grip when wet, I can see where that would be a problem without some kind of grip enhancement. I use the rubber Talon grips on mine, which are adequate for me, but I can also see how the sandpaper texture ones could be better. My gun is normally carried IWB and I wonder about it rubbing excessively with the sandpaper grips. My rubber grips are holding up alright after 2-3 years now, but if I need to replace them I'd probably try their new Pro texture which is a granulate like sandpaper but made of rubber.
