That question is not very easy to answer. I have and use several different guns.

Just got a SS Ruger MK III 5.5 inch hunter model with open sights that I will use this year for small game, but I've been using Browning Buckmark with open sights.

My FA 454 with open sights is my go to revolver.

Savage Striker in 260 Rem with a Burris 3X12 gets the bulk of my use for longer shots
