The following bits will fit all Colt DA revolvers.
I list two thicknesses in each size to account for differing screw slot widths.
.150-2, .150-3
.180-2, .180-3
.210-2, .210-3
Once in a while I would find a "D" frame side plate screw hole tight for a .150 to the point where it might scar the side plate.
So, either stone the sides to fit better or buy .120-2 and .120-3.
