Before I got my SR9c, I used to carry my little Kel-Tec P3AT .380. (Almost identical in size to the LCP).
At first I just carried it in my front pants pocket. It didn't really print at all (I don't wear skinny jeans). Like the LCP, the Kel-Tec has a really long and heavy trigger pull, so I wasn't too worried about accidental discharges, and remembered to keep my fingers out of the trigger guard when sticking my hands into my front pockets.
After doing it this way for a couple of months, I got bored one day and pulled the Kel-Tec out to take it down for cleaning (even though I hadn't shot it).
I was amazed at how dirty the gun was. It was all pocket lint and cotton fibers. Everything on the gun was covered with this stuff. There was lint in the barrel, in the mag well, and especially all through the trigger mechanism. I really had to clean the heck out of it. I went right out and bought a cheap Uncle Mike's IWB holster for the Kel-Tec.
I still carried the little Kel-Tec mouse gun in my front pocket, but inside the holster. The gun never came away dirty again. The Uncle Mike's holster barely added any width so it still didn't print much in my pocket.
