tightloop Posted February 20, 2004 Share Posted February 20, 2004 Started shooting my STI .40 the other day and when I got home noticed that after only 150 rounds of factory ammo the front sight was very dirty. Much more so than with my .45 Commander shooting dirty 231 and lead bullets. Whats up with that and should I replace it after each practice. I don't replace my other one after each practice, probably after 1200 or so rounds. The .40 shoots cleaner inside the gun but the front sight is filthy...any ideas?
