I love my 460 S&W, the grip is perfect IMO and the heavy caliber is easy to handle, I shoot it SA. My buddy has a SBH and even though its a much lighter caliber it is much more difficult to control. As far as loading and fire speed, it makes no difference to me considering the purpose of these guns. I just dont understand the long cane style handle on SA's. Is there a SA made with the grip tucked under like a DA? Is there a good argument for one grip over the other?
