I am the only one that touches my guns and I keep my duty and carry guns fully loaded all the time but before I holster whatever gun I'm carrying I always check it to be sure. Yes, I know it's redundant but I heard a story of a plain clothes cop that didn't check his that one time and lo and behold when he needed it most the hammer fell on an empty chamber. I will not be that guy. Ever.
BTW, I use the "pull" check method described on page one on this thread, not the "press" method shown in the photo. The only difference is that I put my trigger finger on the side of the slide, it gives me more control over it when I pull it back.
