I am not particularly a fan of cleaning my gun. Just wiping it off after a few rounds at the range is all I need, except for the barrel...it does bother me to leave it dirty. Enter nylon brush. Without any cleaning agents, just push the nylon brush through the barrel a few times. Cleans out any loose powder and debris and that's all I want. Leaves it shiny and "clean" enough to carry it again and trust in the next bullet making its way through it. For a routine barrel cleaning (like, every 6 to 20 weeks), I use a bronze brush.
