I try to get out to the range at least once a month.....that is
very dependent on work schedules and other issues. Usually during the fall, I don't get out as much as my cash is going into hunting related costs.
I have a few indoor ranges near my home; they allow a full magazine or cylinder,& humanoid targets, but no rapid firing (you need a minimum of one second between each shot), and I have seen them toss people for not following the regulations. Still, with all the restrictions, it's better than not shooting at all......NONE of the indoor ranges I go to allow drawing and firing from a holster (insurance reasons, don't you know), and if you saw some of the bullet holes in the ceiling, side of the station, ect, it's probably not a bad idea.................
As for concealed carry: I have a place on one of the local State Game Areas that looks like it was made for target shooting....it is basically a parking area within a depression, so there is a high dirt back all the way around (except where the cars come in). You would have to elevate your gun at least 60 degrees to get a bullet out of there. I take my own target holders that I made out of scrap lumber, and my 'humanoid' cardboard targets, and practice on a Sat. or Sun. afternoon. I usually get to do this a couple of times a year; usually in the early spring, and it depends on snow conditions. I can practice here with rapid firing, multiple targets, and drawing from a holster and shooting. Occasionally, I'll get a local who will come in and complain, but I am not breaking any laws (as long as I have a small game license and hunter orange, then I am legal).
And, of course, I do practice....again, when I can, with an UNLOADED firearm, drawing from a concealed position and getting 'on target'.
