I pocket carry, the problem I had with keys is(are?) one time , I was at home, not thinking I dropped keys in front right pocket with gun. and when I went to pull my keys out they brought the gun with them and dumped it on the carpeted floor. I had probably done this before with no problems . No foul , no harm but after that I decided to make darn sure the gun went in the right and keys in the left .
If have some jeans with a watch pocket and have put keys in there, but its separate from the lower pocket and safe.
