RE: Which deer handguns have a flat trajectory?
If you look at the t/c contender or savage striker, you can get them chambered for about any rifle round. I guess if I were going to hunt with a traditional pistol round, I'd probably shoot 180 or 200 gr XTP's out of a 44 mag @ about 1500 fps. Other options would be 454 casull, 480 ruger, etc, but recoil will besimilar to the contender ina rifle round.
