Of almost any semi auto.....
Short version I am anal about my CC gun being clean, I pull a full take down weekly with daily inspection and mag checks..... So I am up in the gun room doing my weekly and I decide to unload the mag for a round check... As I slide out the rounds, Humm kind of sticky feeling....
So I take apart my mag for a closer look.... heaps of fine dust have coated the spring and the inside walls, so I clean it and do a wipe down of everything with a very light oil, works like new....
Had I needed the gun that could have easily been a FTF..... now averted.
