I am not sure if this is a good place to put this but, here goes. I remember when I first got my H&K USP compact .40 and .45 They both had grease for lubrication. I have been using different oils in them. I carry concealed every day. The oils seem to dissipate towards the end of the day. I was wondering if anyone knew what grease came in the or a better grease to use. I know the grease will make more lint and dirt cling to the gun and more frequent cleanings will be needed but I clean them every few days any way. Thanks!
