Hey 243,
Welcome to
For hunting, I would use either a McGivern Bead or Fiber Optic front sight...
And for handgun hunting....I would try to keep my shots to 50yds.
Dot Sights can be awkward in the field, and hard to put on moving game.
If you have a tree stand, you can most often take venison at very close range..
The most important, (and I do this with rifle, as well) is to let the animal GO! if you do not have a SURE SHOT!
4" @ 50yds is very good shooting....
Later, Mark
