I'm looking to purchase my next toy and I have decided I want a big frame revolver. I settled on the S&W 460, but am having trouble deciding which barrel length would be best and if the performance center is worth the extra cost. I plan on mostly target shooting, and would like to be able to carry it. I live in a rural area, so open carry isn't a problem. I'm thinking 7.5" or 8.38". New to the forum so any help is much appreciated. Thanks!
