I'm personally not comfortable with having anything else in or clipped to my pocket when using a pocket holster. I have 2 different holsters I use, depending on pants. I use a leather Desantis model with small or normal pockets then I have a synthetic model, I don't remember the brand, that also has a spare mag pouch built in. This one works better for cargo or square bottomed pants pockets or larger pockets where the smaller one moves around too much. I'm a lefty so whatever choice I use is in my left front pocket. My knife is always in the back left pocket. I've carried a knife in the same place for about 30 years, long before pocket carry of a pistol. I had to start carrying my wallet in my right front instead of the left once I started pocket carry. I'm thinking of moving the pistol to the right front since it's rarely the only pistol I'm carrying. I've also got a nice little pocket organizer that holds my flashlight, a mag for my main pistol and my LCP and my phone. It fits nicely in a cargo pocket if I don't want anything on my belt for whatever reason.
