Blackhawk
Had my 50th Ann. .357 Flat top (4.75" barrel) at the range last week. At 50 feet with a plinking load (158 gr. SWC at 800 fps) I had to raise the rear sight all the way up to hit the paper. Got home and compared it to my OM Flat top (1958 vintage, 4.75" barrel) and determined that the measurement from center of bore to top of sight on OMFT is .743" and NMFT is .845" or a tenth difference. What gives? Time to get the file out? or ?
