i just got a S&W performance center 629 slab side and im going to put a scope on it. i deciding between a burris 2-7 or a Aimpoint 2x red dot? i have long arms and if i crank up the burris to like over 4 power than i have to bring my arms in cause of the eye relief. what do you guys think i should put on it. i'll use it for deer hunting.
