I will probably get slammed for my opinion but here goes.
I DO NOT put any fingers behind the guard spur on either the Contender or Encore.
I put 2 fingers on the curve of the spur and 2 down lower on the grip below the tip of the spur.
All I do is support the gun with the weak hand and take all she has with the strong hand.
The gun recoils away from my weak hand.
I have Never ever had guard spur bite from anything I have ever shot in a Contender or the Encore.
All anyone needs to do is support the gun with the offhand not hold it
Forget the wrap around holds that one tries to use with a revolver or semi-auto. They are not a rapid fire gun so let them do their thing.
There are few calibers that most shoot that one cannot control with one hand while supporting the gun with the weak hand not holding the gun with a wrap around grip.
You doubt it? Here is a video of my 458 Win Mag in action with a 550 gr bullet at 1720 fps from 14 inches.
