I have been hunting for years .. shotgun... rifles.. muzzloaders.. bow.. I know my game.That said i just got around to getting my pistol permit. I am getting this for primary hunting/ tracking. I am liscenced in NY to track deer and carry a pistol for dispatch.All dogs must be on a leash while tracking. that said im thinking shoulder holster under my jacket.Deer size calibers 45.. 44..41 As far as action i am having a hard time coming up with it.Is it going to be DA,SA,Auto.I have only shot pistols 2 times in my life so i will have to learn how to shoot it .So hit me with recomendations ... I wil;l have to draw one handed and shoot too 50 yds for tracking ... Hunting probly a little farther when im comfortable . Barrel length recomendations would be a help.
