Wipe off excess oil that comes out from cracks,trigger frame area ect.. it takes a couple days for all excess oil to drain but Rem oil with Teflon works into all areas and won’t leave a heavy film like CLP. JMO
I use CLP on pistol lubrication points because it won’t evaporate or go away with heat from shooting like Rem Oil (A great product).

Good idea to shoot a few rounds to see what else may develop or your problem may go away.
I had to send in a new 360J before shooting it. S&W returned it in a week with the problem corrected. I feel the pain!

Be SAFE and shoot often!
