cgasperetti,
You might want to pull the firing pins and give them a good cleaning and polishing, along with cleaning their channels in the slides. Glop accumulates here pretty easily.
If you do this, make sure the tip of the pin slips easily through the hole where it contacts the pin... some tend to get burrs in this area, which is easily taken off with 400 grit sandpaper.
