Hello! So, this holiday season my brother-in-law was in town and we went to the range. He was very glad to help clean the firearms we fired and was anxious to show me how he cleans guns. I took him to the NW Armory and He had my buy an aerosol can of Break Free CLP. Once home, he proceeded to hose the living daylights out of everything in sight. I have since managed to remove it all, from my XDM 9mm 4.5", except in one particular tight spot: the very rear of the frame, there is a small spring assembly, Im presuming assisting with the firing pin mechanism? Is it bad to have that area over lubed? Should I take it to a gunsmith to have it taken apart and cleaned out? Am I over thinking all of this? Any thoughts are greatly appreciated! Thank you!
