So my carry gun Ruger SR9c I take it out of the safe in its IWB holster loaded with a round in the pipe strap it on and when I come home it goes back in the safe that way no issue. The question I have is can the round in the chamber rust or carode from summer heat and or humidity? And how much oil do you coat the chamber with? I was taught that oil can be a big no-no to a chamber since it can creep into the primer of the chambered round thus having a dud round?
Also how long should you keep your defensive rounds before shooting them and replacing them with new?
