The DP Pro on my .45 carry gun went a full year before the battery went. Way longer than what I was led to believe when I was looking into it. How long have some of you’alls lasted?
I'm a little surprised. I would expect more then a year. My Aimpoints and Trijicon RMR get new batteries once a year, but the stated lives are much much longer. I assumed a new DP would be similar.
