Father-in-law drew back my brand new Chill and let it go. Peep was knocked loose, monkey tails snapped, and I was irrate. Why would you need to draw someone elses bow without a release is beyond me. Of course he never apologized either. Took it back to A1 in Hudson WI and they set it back up. My wife, who gave it to me as a gift, wanted to smack him. Never again will I let anyone touch my bow.
Sorry to hear about that unfortunate incident. I've got a brother in law who did the same thing with my Z7X, I hadn't event put an arrow through it ye at the time, thankfully he let the string down easy and no damage was done. He went from "can I hold it" to full draw with bare fingers in an instant. He no longer touches my bow, and I no longer let anyone hold it without an arrow nocked and a release on. I'd definitely tell the pro shop to give a good look at the limbs and cams before I put an arrow through it myself. I got him back tho, at a later date he asked to see it again. So I nocked and arrow and gave him my release. My bow is a 30" draw, he's a 28". One shot and he had bow slap from his elbow to his wrist with a bleeding raspberry instantly. He hasn't asked to "see" my bow ever since.
Make sure that they also pull those axles and check them for straightness as well. Personally, I NEVER draw back my bow without an arrow on the string (and a safe backstop). I don't mind allowing someone to hold it, as long as I'm right there, but I always tell them not to draw it back. I had one guy get a little offended and say "I'm NOT going to dry fire your bow". I replied that no one ever dry fires a bow on purpose. V
1. Never, ever draw a bow without an arrow in it. 2. Nobody but the owner ever draws the bow. Two super easy rules that totally eliminate the chances of ever having a dry fire.
Before season I like to just practice drawing to get my muscles in shape, usually a few draws then wait a while, and repeat. Putting an arrow in it every time was a hassle, so I bought a TruFire Draw Check. It's what you see used at pro shops. Once it's hooked on, the bow HAS to be eased off before it will unhook. One of the very best archery accessories I've purchased.
There would have been a knock down drag if that was me. There almost was when my brother looked like he was going to pull mine back.
