Dr rear sight

Weigand makes a replacement rear sight for a S&w 14 series revolver that is approved for dr matches my sights do not regulate so I’m going to replace them and think this would be a good option ??? my question is of the three rear widths .110 .125 .140 which would be most desirable for dr targets and what front width blade would suit the rear ?? I do not have any experience in this type of shooting so a reply of it’s what you prefer will not work for me because I don’t have a preference and there’s no one around me to see what others use .

It is NOT approved for NRA DR matches.
It is only approved for  NRA Police Combat DR.
Don’t confuse the two!

So were it says and Distinguished Revolver Matches is wrong

Sorry about all the pictures new to this system

Sorry about all the pictures new to this system . So a nra distinguished revolver match is different then this this one.

Yes, they are referring to the PPC DR match.  The DR match we shoot is in the Precision Pistol Rule Book.  Two different things.

Glad I asked thanks
