Swap between Buffington and ramp backsights?

[Dick Hosmer]

The rear sight hole spacing, location relative to receiver, and threading are IDENTICAL for ALL .45 caliber trapdoors, period. The screws do change, and the lower band is different as to top profile. However, all of the components are readily available at a reasonable price, and may be swapped in less time than in took me to type this. So, "no worries"!
