Magnums in these lightweight guns is nuts, says I.
Get some 148gr wadcutter .38 rounds for practise. Most people can't hit the side of a barn with a snubby, from standing inside the barn.
So extra recoil and flinch are not the way to develop good revolver skills, unless your name is Berto
Work those wadcutters over time, working your way up to .38+p for carry. Leave the magnums to your buddy.
End of unsolicited advise to those with revolvers under 1 pound
