Picked up a sweet smith and wesson 629 6.5 inch in 44 mag from a member here. I want to make this a hunting gun. I'd like to put a scope on it. I know nothing of handgun scopes. After some googleing I found scope options are pretty slim. Not sure if I should do a fixed power or adjustable. I was thinking a 4x. Any input on a good solid mount or the 629? I was thinking of getting this chest rig to carry it while hunting.
