As said, a simple request - only kind I can understand... I have a Ballester Molina .45 ACP without a front sight: lost it during a shooting session. Novak has a great selection of replacement sights that can be fitted, but in trading emails with them they want to know how tall the front sight is. Not something I can answer. Anyoune with a spare B-M front sight in their pocket; measure it for me...or if you have experience in these things give a yell. Thank you in advance. Contrarian.
