I own an FSX-FO which I find unique in that it appears to be the 1st slingshot made that actually has a sight located between the forks that works. Since the sights rotate out of the way, they won't get broken off or interfere with my shot. This helps put the target right in the middle of the sighting line so that I can adjust the reference points located on the sights with respect to the target. I don't think the sights are hitting you in the hand; probably the rubbers when they snap back after you shoot. Usually this happens if the slingshot is not held correctly when you release the bands. When I shoot a lot I wear a small leather glove. It has a solid aluminum frame which won't rust, unlike those made of steel. Very weather proof and could be left in the rain. The pouch may dry a bit stiff.
