Last week I went to the range and had my first ever FTE. Not saying it was due to lack of proper lubrication 100% for certain, but it made me cringe a little. It was the first time I had used that range and their ammunition. Could have been that too, who knows. I lubed it up in May last but just kinda applied it on moving parts, not really taking into consideration amount or where to. Sure ain't the right way to go about it, but it was better than doing nada. I knew not to have gobs of oil everywhere and have it running out of every hole on the gun, but this time around I want to give it a proper lubing up. Anyways, I bought some Gun Butter after reading numerous good reviews and would like to lube up my XD9SC. Anyone with a good how-to that applies to all guns, or any XD owners who could chip in and give me some help here? I've Googled the hell out of "how to oil a handgun" and various other entries, but I can't seem to find one good explanation about what truly needs oiling and what does not.
