I'm working on my second 1911. My first was a Rock Island as a 'practice' round- polished the feed ramp, the trigger sear, the trigger slide sides, and disconnector. Seemed to work well- no malfunctions, and for the most part very smooth.
Now I'm on my second- a Springfield Range Officer. The trigger is incredibly gritty and the slide sounds like it's scraping on sandpaper! So I'm going to tear it down and polish up the areas mentioned above, but I'm wondering if I'm neglecting some areas. I've heard some talk about polishing the strut pocket in the main spring housing (not entirely sure why). Is there anything that a professional 'smith would normally do in order to improve the platform? My main concern is the trigger and frame grittiness as well as the slide.
So can I take my Dremel and some Flitz and polish the slide grooves (both on slide and frame?)
How do I polish the areas between the trigger and frame? (tight area) Tiny files?
