I have a S&W 629-6 mountain gun with a stock black rear blade mounted on the rear sight assembly.

I want to change the rear sight blade with one that has a white outline from Midway USA but there are different blade sizes.

I do not know what size blade comes stock with the revolver?
ANyone know the answer to this question?

I am the original owner also.

I have a 629-4 Mountain Gun and I put a white outline rear along with a red ramp front on it. All I did was call S&W and told them what I wanted to do. They sent me the correct height sights to change them out. Both sights together cost about $30 if I remember correctly. Give them a call, they will get you what you need.
