Given the abuse I and my coworkers put our issued duty pistols through, I wouldn't worry about it one bit. My duty gun has eaten dirt, eaten pavement, eaten barbed wire, and any number of other things, and that's all while it was holstered! I dislike the model they chose for us, but I do have to admit it's been 100% reliable, even with the scratches, dings, and a couple of outright slams on it (with my body weight behind them, no less).

If there's any doubt, unload your gun, do a function test, wipe it off, reload it, and put it back in the holster.
