My son has a 439 and wants to change the sights to a modern 3-dot system. How/where can he get this done? Any help will be greatly appreciated and I thank you!
I don't recall how the sights on my 439 were set up, but check out Novaks
Their website shows everything they carry and all their charges , I just got a Colt back from them and their work is impeccable and fairly priced.
I was very happy.
