I have watched several YouTube videos on cleaning a Glock and they all mention about "the most important place to oil your Glock". The manual says "A drop of oil is needed where the rear end of the trigger bar touches the connector at the right rear corner of the frame." I just cleaned and (tried) to oil my Glock 23 and I'm just not sure where this magical spot is. Does anyone here have a close-up photo and indication of exactly where this is? Any help would be much appreciated.
