This. I was using an Uncle Mikes' holster which was great, but the slide was rusting around where it touched the holster's upper lip. After cleaning slide with fine steel wool and putting on some dry lube, I switched to a DeSantis and so far no repeat of rust (though real test will come this summer when I mow the lawn).recumbent said:You might consider a holster that has leather between your body and the slide.
