I do around 30-45 minutes of dry-firing a day, about an average of four days a week. Mostly stuff like "blind" magazine reloads, strong-side, weak side and offhand presentation. Tactical magazine changes and speed magazine changes on the move, every direction (yeah, even backwards). I just try to keep my head focused on what I am doing and ask myself afterwards why I was doing what I was doing. I love having a partner while doing these, an extra set of almost-objective eyes is really useful.
I try to get as much bullet time as possible, as my job is mostly carbine work I have to find my own time for handgun drills. I can usually afford a couple of ten-round drills a week. When I don't have the ammo, dry with caps just has to do. I try to push myself a little, distract myself with loud music that I don't like... things like that. I don't have a CCW in this state yet (just got here three months ago) but when I do (in a year and-a-half) nice to know I'll be ready.
