RE: laser sight return to zero ?
New use for laser sights for you "corporate" types?
Okay, completely off the subject, but something I'll always remember. The Army lives and breathes on PowerPoint briefings. A few years ago while in a briefing room at FOB Speicher in Iraq, the General being briefed had Crimson Trace added (probably not authorized) to his M9 (Beretta) 9mm service pistol. When he'd have a question about a particular PowerPoint slide, he'd point it out using ..... His "laser pointer". Of course, bringing a new meaning to the term "hostile briefing".
Don't know if some freaked out staff officer finally drew his own pistol on the guy, but guessing that a bigger general finally told him to knock it off.
