One of the most important things I did to improve my handgun performance was to get a pair of shooting glasses.
The left lens is my regular bi-focal, so I can see the distance ok and also can see the bench for loading mags, etc. The right lens (shooting eye) is optimised for 33" so I can see my front sight clearly. The optical center of the lens is displaced up and left, so i am looking thru it when my head is in the aim position. With cheap frames they cost me $50. Best $50 I ever spent.
If you are over 40 you might want to consider how well you can see the front sight.
In my log book this is the $100 Rossi. Another gun I scored on EE.
My 357 Taurus. Don't know what model it is. They don't mark the model on their guns. ???
One of the few that did not come from EE. This Ruger 101 if from a shop at Port Perry. Only $250 (used).
Not only is it a short barrel, but an Airweight, too. But it shoots well.
One of my first Norincos. I was very impressed and now have a dozen or so. 200gr SWC and 6.0gr 7625 A medium power load.
Probably my best pistol. Has a fabulous trigger.
Each pistol has a load that it does best with. But 20 9mms can share only 3 different loads, so logistics are not too bad.
