Someone is making a trigger release that fits in the palm of your hand, now (although it IS a strap style release). The trigger is operated more back in you hand. If target panic (or the like) was bothering me....I'd give this release a look.

Also....my Scott Sabertooth is adjustable to be able to utilize the second knuckle of the index finger.....further back in the hand.

If I were to be able to give you any advice on something I had familiarity with....it would be this.

Good luck.
