The OC trigger is awesome. I kept tight groups and the reset was way more predictable/easier to time. I'm going to order one for my 30S. Now if I can only just get my Glock 45 to not shoot low and to the left LOL
If you take a piece of 2000 grit sandpaper and polish the striker face gently (just enough to eliminate the roughness) this helps triggers quite a bit, too....
