If you want to hunt with a sawed off rifle, go for the contender (no offense to single shot pistol fans). Shooting a CF rifle cartridge out of a 14" barreled stockless rifle isn't quite the same as using a 4" or 6.5" revolver to hunt with. I just don't see the point, but I have not been bitten by the single shot 'handgun' bug.

If you want to hunt with something that resembles an actual handgun, get the 629. And a case of ammo. And shoot at least half of that case at various ranges using field positions to gauge your maximum effective range. Then go kill a deer.
