I recently purchased a 1976-1977 model stainless security six with a 2.75 inch barrel for 100.00. After nickel and dime purchases on gunbroker, Numrich, and a Wolf spring, I am in the pistol about 150.00. I bought the front ramp sight from Numrich and it is for "Pennsylvania Trooper models,"(as thtis was the only sight available) and is too large. Everywhere I have checked states that the sights I need are "discontinued by manufacturer." If anybody has a decent one laying around, or has any ideas on where to find one, it would be much appreciated. Thanks, jmelcock
