Don' t feel rained on, BuckAlley. I' ve seen more than a few guys knock themselves plumb cookoo like that. I' ve seen ' em bust their noses and knock teeth clean out. One guy had a glass jaw and scored a KO on his ignorant self. The release went off as soon as he hit peak draw on that 80 pounder and his fist whopped him right on the point of the chin. He was clean OUT for about 5 minutes. It was the 4th or 5th time his release had pre-fired that day and he just kept on shooting it instead of pulling out his spare. It' s been some 18 years and he gets reminded of it regularly. Especially when it' s his turn to buy drinks.
Next time you decide to play with a release, don' t draw directly toward your anchor. Draw to your shoulder. When you' re at full draw, then - and only then - bring your hand up to your anchor. That way, when the release malfunctions (and they ALL fail, eventually - some sooner than others), you' ll hit your chest or shoulder instead of popping yourself in the eye or busting your own self in the chops.
But do send that release back. My TruFire has always functioned perfectly in both modes.
