Blackhawk
Went to the range with an OMBH FT (1967 vintage) and a NMBH FT (2005 Anniversary) 357 Mag, both with 4 5/8" barrels. OM shot to point of aim with rear sight slightly elevated. Mild load. Had to crank the rear sight on the NM almost to top in order to hit same spot on target, same load.
Got the micrometer out:
OM barrel: .700 diameter
NM barrel: .729 diameter
OM front sight: .396
NM front sight: .497
Distance from center of barrel (.350 for OM, .365 for NM) to top of front sight;
OM = .746
NM = .862 or .116 higher.
Comments, suggestions, other than the file trick.
