One of the advantages of having your own ranges out your front (and back) doors, and no neighbors, is that you can shoot whenever you want.
I don't know what the stats are, but I would bet that there are about four or five to one odds that a self-defense incident involving firearms will occur in poor light. So about every month I go out around dusk and burn a few. I have 2" and 3" steel swingers and a 12" gong that I work with from 7 to 50 yards. My goal with the freshly painted gong is to put about 100 rounds on it and have them centered for the most part in a 5-6" dark grey cluster for all ranges.
Tonight I worked 'til the muzzle flash was distinctly distracting (a good thing) and I could not see the sights any longer (not so good). But it was a good session and I recommend that sort of thing to anyone who carries a handgun, even occasionally, for defensive purposes. Shooting in well-lit circumstances all the time is dangerously misleading. Shoot in bad light regularly, if you can.
