I'll start this with the fact that I have been shooting with a scoped handgun probably 100 rounds to every 1 shot through a gun with open sights of anykind because at my age a scope is easier to see with. That said, I carry a fix sight revolver, never had adjustable sights to fail, but like to know that my sights are as solid as the frame. A single action, large bore revolver with sights and load that shoot together is unbeatable for me. I want a blade flat and a slot cut in the frame big enough to see air on both sides of it. The way I practice is shooting the little saber tooth chipmunks. When you hit one of those on a regular basis at 20 to 30 steps anything else is easy money. Is a 44 or 45 bullet a little over kill on the little critters? I don't really care, the rednecks that got here before me killed out all the lions, tigers, bears, and dinasours. I'll walk down behind the house and shoot a deer for meat every now and then, got to lazy to do that lately. Knowing your gun hits where it points makes it easy to shoot anything. Choose the kind of sights your most comfortable with, if you haven't shot thousands of rounds like some of us old folks use adjustable. Gettin old and can't see the little darlings use something optical. I started this with the fact I shoot a scope a lot, I love a Ruger Mark 2 with a 5 1/2" barrel and scope. Try to run a few hundred rounds through one every week. It is nice to be able to see and hit things again, and a scope does that. The person that comes up with a set of open sights that work that well will make a good living just redoing my guns, and the rest of the old folks here.
