I was pleasantly surprised when I first held the P07/P09 grip. I normally stipple or grip tape all my pistols, but really I like my P-09's factory texture. That said, I've only had a few range trips in cool weather. I am in SE Texas, so I will be able to test the sweat factor very soon. Traction Grips may be in my future as well. I have them on other pistols and have gotten them very sweaty and wet with no issues, but Gunscrubber cleaner will blast them right off.
