After several weeks of carrying I'm noticing lint buildup on the inside of my glock and on the outside around the muzzle. No huge pieces or anything, but if I look closely at the inside of the slide, I can see small fibers everywhere, especially on the oiled surfaces. I'm sure this is normal, especially since I'm carrying IWB with a holster that leaves some of the slide exposed (so my shirt/coat is rubbing against the slide), but it's still probably not great for the gun to have all that junk in there. This brings me to my question. How often do you clean/check the gun that you carry on a daily basis?
