Same thing happened to me when I carried my Karas Kustoms Retrakt clicky pen. I was using a capless rollerball refill at the time (a pretty wet refill). The click mechanism got pressed while clipped onto my pants pocket, and next thing I know my friend was asking about the ink stain showing on my pants. I still love the pen, but I don't carry it in my pants pocket anymore. I've had a lot more luck with screw cap types and bolt actions. I would recommend the Karas Kustoms Render K, or the Brian Fellhoelter TiBolt. Both of them are very sturdy and well made. If you're really worried about ink stains, I would run a ballpoint refill instead of gel or rollerball, although I run rollerballs in both and have not had issues. Both have many refill options available. The Render K is amazing for the price, but I find myself reaching for the TiBolt a little more often; I really like playing with the bolt mechanism when I'm not writing.
