I put a Hi Vis on mine. And taking a correct sight picture it does shoot Waaay Lo.
The main mission of my LCR22 is as a practice J Frame size revolver. Cheap to shoot, and no recoil. It is a great revolver to put in a lot of trigger time with.
I have shot it in Defensive Pistol matchs and done fine with it.
How I do this is to put the Fiber Optic Ball on top of the strap, and not down in the trough.
This has worked ok for me, and what I am doing with it. I also have a couple speed loaders for it. For speed strip practice I load 2 and skip a hole for cylinder clearance.
For anyone who wants better than combat accuracy sight paint is probably a better answer.
