As your experience increases with the 1911, you will understand my question.
The sear spring (that three fingered piece of flat metal) does the following:
- Port side: Keeps pressure on the sear to help with reset.
- Middle: Keeps pressure on disconnector (pushes up) and trigger (pushes forward)
- Starboard: Keeps pressure on grip safety.
Look at the middle "finger" function. If you pick up a good book on the 1911 (I recommend both of Kuhnhausen's), you will have some great knowledge at your finger tips.
