[This would be my first pistol, I want something that's fun & that would be good for deer hunting.]
BTW - I don't know about the "fun" part - but IMHO, if you're gonna hunt with any handgun, you better get used to a two-handed hold, either the Weaver stance or and isosceles hold or a variation of either.
What works best for me, when making a hunting shot is a "push/pull method, wherein I push forward with the main grasping hand (the one with the trigger finger) and pull back at the same time with my other hand, which is wrapped outside the grip and main shooting hand. It locks me in solid, and I can easily pivot at the waist for moving shots.
