Hi folks. So I was cleaning my Glock this morning and no matter how many times I run my patch through (with Hoppe's) I'm still getting black residue. Now, I am pretty sure that I only cleaned it with dry patches two weekends ago as an oversight (yes I'm a newb) so this is the first time in 2 weeks it has really been cleaned with Hoppe's. I shot 100 rounds through it 2 weeks ago and then 150 last night. Every time after I put the bronze bristle brush through then run a Hoppe's patch through it, it's still coming out with black. I did this for about 40 minutes switching back and forth between the wet Hoppe's patch and the bronze brush. Am I ruining the barrel? Should I still be getting black **** on the patch? Not sure if I should keep proceeding until the patches are clean. Thanks.
