It happened again today. A member on the line took a pistol out of the case, pointed it to the left and up at the head of the person next to him while he slid the plastic bag off of it. Slide was closed and mag in gun. (I've previously been on the muzzle end of someone doing the same think while locking the slide back on a just uncased 1911.) I did the usual. I immediately let him know what I observed. The man to his left did not notice (they were both uncasing guns). I advised the range officer who will identify him, also talk to him, and notify our chief safety officer. I left, because I did not feel safe. Beyond that I'm not certain what will occur, but I intend to check on it, because it happens all too often. This time and the last time it was experienced shooters (70's and 80's of age). This should be second nature to a seasoned shooter but apparently it is not. After one incident, a new member replied "it's not loaded". He quickly came to realize that was the wrong answer. I estimate that I've had guns pointed at me at least a half dozen times in 5 years, all at the same club. Does anyone else's experience approach that number?
