I got a 5 round sub 1 inch group at 100 yards with my mismatched LB with PH5 sights the first group I shot with it. I thought I was awesome! I thought it was awesome! It never happened again though, not anything like it. I never ever replicated the completely relaxed "just fire 5 in a row to see what happens" type of shooting ever again and that has the biggest effect of the results.
