The manual is very vague about where to place the oil. There are many methods for cleaning Glocks and no specific one is better than the other. With Glocks, less is more. They do not need more than a total of 4 drops, ever. I have put my carry G19 through its paces as well where I cleaned it dry of ALL lubricant and ran 300 trouble free rounds through it. After disassembly and cleaning there was no damage done.
My supplies for cleaning are:
Mil-Comm MC25 (I like this cleaner as it has no lubricant in it and it water soluble. It is more of a mild degreaser and detergent than anything. Choice of cleaner is subjective and there really is no wrong choice.)
Royal Purple Synfilm (I like the weight of this lubricant and that it does not get absorbed into the porous metal as quickly as some others. Again, this choice is subjective and there really is no wrong product to use.)
A boresnake in whatever caliber the pistol is. (Patches and a cleaning rod will do just fine, but I prefer items I do not have to dispose of.)
A toothbrush, rag, and a couple q-tips.
My routine for cleaning is:
Field strip the pistol and spray everything down with Mil-Comm MC25. Use the toothbrush to scrub everything and then the rag to wipe everything dry.
Use one of the q-tips to get the cleaner out of all the places too small for the rag to get (around the trigger bar, inside the striker channel by the lug, and around the barrel lug).
Run the boresnake down the barrel a couple times.
Get a bit of oil on your finger and coat the outside of the barrel and inside the slide where the hood of the barrel contacts it. (After a box or so of ammo, this area should be apparent as there will be visible marks where this contact is made) Apply a small drop inside the barrel lug and allow it to spread out. At this point, I use what is still on the tip of the oil bottle and wipe it across the 4 metal slide rails on the frame. (This ends up being plenty of lubricant even though it doesn't sound like much) Apply a small drop to the area at the back of the frame where the trigger bar contacts the connector.
Reassemble the pistol and function check. Rack the slide a few times and wipe of any excess oil or detergent you missed.
This has worked for me for years with no issue and uses enough lubricant to slow wear while not making a mess when firing. This is not the right or wrong way, just what works for me. You will get different answers from everyone as far as what to use and how to use it. This happens to work for me. Find what works for you.
