My father had purchased a used Glock 22 several weeks back that was just drenched in oil plus there where metal fragments all throughout. I kept wiping it down but it was like an artesian well of oil and grit was located somewhere inside.
Since I was getting many FTF's at the range and the trigger assembly felt gritty no matter how much I did standard cleaning, I decided to just wash the entire lower. I fully disassembled it and using some warm water and Palmolive, I thoroughly washed it along with all the parts except the 3 pins. After rinsing and drying it completely I reassembled it, adding only the tiniest hint of Rem-oil to the contact point of the trigger bar and connector as well as the rails.
The slide action and trigger pull now feels brand new again. Anyone else done this before?
