If you can't kill a deer with the 44 mag handgun then bigger isn't going to help you . The 44 mag with a 240 to 300 gr bullet will down any deer out to a 100 yards if you hit them where they live. My favorite hunting pistols is my 4 inch 629 and 4 &5/8 Ruger Blackhawk , both loaded with Keith 250 gr SWC, 20 gr of 2400 and the CC1 300 Primer. I have a bunch of longer barrel handgun but prefer the 4 inch in the deer woods. If you can't hit with the 4 inch i seriously dough 2 more inch's of barrel will help you. What you need is more practice not barrel length ,
