bend barrel
Sir;
I don't think your barrel needs bent at all.
Most right handed shooters will, yea, "flinch" to the left and most all left handed shooters will, yea, "flinch" to the right.
In a gunfight (if you are aware and agile) the very first thing I do (being right handed) is to draw and slightly move or side-step left because most bad guys cant't shoot for s---!
Have a buddy load your revolver and hand it to you with an empty cylinder under the hammer and you will find out very quickly why you're hitting to the left (or right) of the target!
Now, this might not be your trouble, and if not then something must be done. And, The las thing in the world would be to "bend" yor barrel. Checking the crown is essential - this can move you three or more inches off!
Fixed sights on a single action are (from Ruger) I think (?) are laser aligned.
Now, if indeed this is a physical problem of barrel/frame misalignment send it back to Ruger and they will repair it - this complaint you express is very common and usually is "pulling" or "flinching." I'm not demeaning your shooting ability - I flinch too if I'm not careful! Particularly with a 480 Ruger or a 454!
But there are other ways to correct this than bending a barrel. Yes, I've straightened barrels but never "bent" one to correct P.O.I.
