Hi,
First time gun owner here so this is probably a stupid question. I watched some Echelon cleaning videos on YouTube and they caution on getting cleaning oil in the firing pin hole. What will happen if cleaning oil do get in the hole? Will it cause malfunction or worse, possible accident?
Welcome to the obsession.
As has been mentioned, oil can attract dust, soot, dirt, and gum up the works. Worst case scenario, if you start getting light primer strikes you can clean the striker channel. Or let a gunsmith do it. But you'd really have to mess things up to cause it not to fire.
I use a two stage system to clean my guns, Shooter Lube. It has a solvent to clean and an oil to lube. I don't worry about getting a little spritz of the solvent in the striker channel but I do my best to avoid it. When applying the oil I put a few drops on a Q-tip and apply it just where needed.
After cleaning your unit a couple times you'll develop the procedural details that work for you. Read the manual, check more Youtube videos, get tips from your local gunsmith, etc. You're on the right track.
I have an Echelon 4.5F comp, as do others here. Happy to help!
Thank you for your indulgence,
