Hi, I am having an issue I wanted to ask about. My carry gun is a kel-tec pf-9 and pretty much I have wipe out the barrel every day as it collects a good amount of dust on the inside just from a days worth of carrying. Is this normal? Should I worry about this and keep cleaning it every day or is it no big deal. Also I do put a very very light coat of oil on the inside of the barrel to prevent rust, so Im sure this is why it sticks so bad. Any advice?
