You want your wrist strap to be tight enough so that it won’t slide off, but not too tight. If you’re using a release for target shooting, you may prefer it to be slightly looser than average. However, if your release is too loose, it will slip down your bowstring whenever you shoot an arrow or take your hand off the grip. This could cause it to catch on your bowstring or arrow rest during release, which could potentially damage your equipment and injure you. If you’re using a wrist strap for hunting, then you should make sure that it’s tight enough; otherwise, your buckle might slide off when you take your hand off the grip. This could potentially put your bow in the wrong position at the wrong time, leading to an unsuccessful hunt.
