While at the range I was shooting magazine after magazine with the light constantly on. I then switch to shooting with the strobe on and while in the middle of a magazine, the light turned off. I finished up that mag and went to try the strobe again but his time no strobe, light still works with momentary and constant on. Came home read the instructions on how to enable/disable strobe, that didn't work either. Shooting both Remingtion UMC 180grain and Blazer 165grain. I don't remember now what round I was using when the strobe turned off. Anyone else ever had this problem? I had no other problems shooting with it. Thanks!
