a 357 hammerless Taurus 605 gun is very accurate out to 20 yds, but with Speer Gold Dots it hurts my trigger finger, the guard is almost to small, (it is the same size as my son's S&W) took the top off of my knuckle hurt like crazy.
Wish they made the guards a little larger, but of course most do not have my large fingers the trigger finger on my right hand is a size 24.
Well I guess I will just use +p+ 38's insteed of 357 it carries great just drop it in my back pocket and go.

I think part of the problem is this revolver's grips. The top finger groove directly behing the trigger guard is too small for someone who has large hands, as you apparently do.

The .357 Magnum cartridge is an excellent one in many ways, but I don't think it's an optimal choice for use in small pocket revolvers. The problems you are having should have been easily predictable. Changing the grips may help. Going to a +P .38 Special will do even more.

I will not shoot 357 in it again so I only have two options 38+P or trade it.
