This is my competition VP9. Similar to bystok's pistol, just the removable panels are stippled. The stippling gives a noticeable increase in grip, especially in the summer when things can get hot and sweaty.
One word of warning, if you shoot a high volume in a compressed time frame, you may find yourself losing skin on your hands due to the stippling. I've ramped up to 500 round practice sessions the last two weeks leading up to USPSA Production Nationals, and my hands are pretty raw at the moment.
