I am always at a loss, on a NRA-style pistol range, where one is limited to shooting at 25 and 50 yards.
When I was shooting a lot, and even in competition, 25 yards was extreme pistol range. It's the point at which you think seriously about switching to a rifle (or a carbine).
I normally practice out to 20 yards, although in my old age I'm not doing very well out there, either.
If I were confronted with having to make a 25-yard shot with a pistol, I think that I would drop down to prone, just as I used to.
It takes me longer to get there, nowadays, and it's really hard to get back up, but it does certainly improve my ability to make effective hits.
The prone position I use makes a 45° angle to the target, with my feet to the left and the pistol centered. I am rolled slightly onto my right side. I shoot with bent elbows, but still in the Weaver geometry, with an almost-straight right arm in contact with the ground.
With your pistol firmly in your right hand, and from the beginning Weaver position, you collapse to your knees and catch yourself with your left hand, lowering your upper body into full prone and then rolling onto your right side a little. Meanwhile, you've been pushing your right hand forward and leftward, to meet your left hand for a two-hand hold.
To do a reload, you have to roll further onto your right side so that the dropping magazine clears your body, and you have room for your left hand to grab a new magazine and push it in.
It's easier to do than it sounds...with a little practice.
So there's a 25-yard drill for you to work on: Go to prone and make a few hits. Get back up. Do it again.
