Unfortunately, we are not allowed to draw and fire on any of the ranges here; rapid fire on the ranges is forbidden as well (maximum of 1 rd/sec, and they keep a close eye on you, too!

)
Personally, I practice at the range by bringing the gun up from a low position, quickly alligning the sights, and firing one or two rounds. At home, I practice getting my gun from my holster (empty, of course), and the sights on target as quickly as possible.
During early spring (March or late February), I try and take a couple of weekends and go to the local state game area and put it all together. I have found a spot that is a parking area and has a burm that goes up for several feet around 75-80% of the parking lot, so the danger of a stray round getting away is minimal. Most hunting seasons are over at this time of year, so I am not going to bother someones hunting with my shooting, and I can practice with an over coat on (pushing it aside to get to my weapon). I usually set up 2-3 human sized targets on platforms that I made from 2x2 stock and some old stair planking....the targets are made of scrap cardboard from work.
I set up the targets, try and get two rounds in the closets first, farthest last, practicing at various distances.
I also use this opportunity to practice with buckshot from my short barreled scatterguns as well.
Any other suggestions would be greatly appreciated.
Due to work constraints, I don't get to shoot as often as I like to, but I try to shoot with my handguns at least once a month.....this time of year is difficult, as the deer hunters are starting to sight in thier rifles, and the range gets packed pretty quick.
I have seen the 'fire a cylinder or magazine full of ammo' and then consider themselves 'good to go".
