Sight blade help - .126 .146 .160 - which height for which model / purpose?
I have 3 S&Ws which need rear sight blades for various reasons.
One is a pre model 29 4 screw 6.5in, the second is a 27-2 6in, and the third is a 686-3 4in.
I want white outline rear sights for each. I see that S&W carries them and I found a gunsmith to install them since it can be tricky or so I've read (I never did that before).
I'm wondering which sight height is a good choice for each model. For the 686-3, its going to be 50 yds or less shooting most often. For the 27-2, perhaps out to 100 yds. For the pre 29, I may want to shoot farther, so I want that opportunity.
I'm thinking for the 44 mag, since I may attempt longer shots, so .160 ? For the 2 357s I'm thinking .146 rear white outline sights. Am I right to want those sizes? Can anyone recommend anything? What sizes would they be from the factory?
