whoa!!
filing down a sight is making it shorter. If shooting high, you need it taller. Call Ruger and have them send you a sight blade for the 45 Colt blackhawk. They are a little taller than the .44. Drive out the roll pin in the front sight and pull out the blade and insert the new one. About a 2 minute job with brass hammer and pin punch.
