Well... what are you using them puppies for? I also like to have my pistols/revolvers/rifles/projectile firing weapons zeroed to the range I am going to use them at. BUT... are you target shooting at formal range, are you just plinking, are you using your revolving pistols for self defence?
I realize on this forum we are generally speaking about fixed sighted handguns but that covers a whole buncha ground.
Please to have some more specific info
