It came to my attention that I need to wipe down my carry more often in the summer. I went to do it the other day because I noticed some lint build up. I carry IBW and lint happens. This time I noticed some rust on the front sight. This is the only place that is just steel on the gun (LCR). The only thing I can figure is sweat, it was at the drip point. It has been hot for here and I have been doing alot of heavy yard work as well.
