So I've fired 500 rounds through my G-19 now, which was bought new, and just cleaned it for the second time. When I go to the range I put about 100-150 rounds through at a time so I'm going with a schedule of about once every 2nd visit or so, but I guess it really depends on how much I shoot and how dirty it gets. I'm not too concerned about when to clean the gun since I know they're reliable and I figure as long as I don't neglect it I should be alright. Anyway the first time I cleaned it I followed the instructions on this video. It ended up spotless however the oiling instructions in the second part pretty much have you putting oil everywhere. In fact I had to wipe it clean because there was just so much oil but I followed the instructions and reapplied oil in all the same places (pretty much everywhere inside the slide and on the barrel, avoiding any holes, the feed ramp, etc.) but a much lighter coating. After I went back to clean the gun the second time I noticed a lot of debris for a relatively small amount of rounds fired. I know oil attracts debris like a magnet so I decided to follow hickok45's video. Overall he seems to advocate a much more dry cleaning method rather than using solvents, oils, or any types of liquid (except alcohol which is only applicable when the gun is very dirty) particularly with respect to the slide. I've also watched a few other videos where people would douse the entire slide in liquids that come in a can like rem oil as a first step and wipe it down completely. I winced watching those because I knew they had to have been getting some in the action although I don't know if they were using oil and I don't know if other cleaning products will attract debris as well. So basically my question is; what is the best way to remove all the carbon from the slide? I liked hickok's method because it left very little oil on the gun and generally a dry slide save for the grooves. Getting the debris off isn't much of a problem and I recognize that oil will cause more to accumulate. However without using any kind of liquid during cleaning it took me quite a while to remove the carbon and even now if I were to take a q-tip and run it aggressively against any part of the slide I'm sure the cotton would have a lot more carbon residue on it than it looked like he was getting in his video. As of right now I probably still have some carbon on the slide but it looks clean and, more importantly I think, it isn't covered in oil so it won't attract large amounts of debris in the future. Is it necessary to get all the carbon off the slide or is that a battle I can't win? Also I realize I could combine what I like from both methods but using rem oil to clean the entire slide doesn't seem to make sense if you're trying to avoid getting any in the action. I'd stick to hickok's method if I knew that having carbon in the slide didn't really matter if it wasn't in excess but I always figured when cleaning I should remove everything. Sorry for a bit of a long-winded post, I just wanted to cover everything. I'd appreciate any advice/help with this. Thanks.
