Here's an example of my shooting at 10 yards (8" black part of target): (New Walther PK380, .380ACP Federal ball ammo)

It was bloody hot inside the range and as the time there wore on sweat in my eyes really started to take it's toll on my shooting.
I need to work on getting some ammo for my newly acquired CZ52. (read that as save up some money, unemployment sucks)
I don't know how an experienced shooter you are, so here goes:
What order did you shoot in, or don't you remember? It seems you may be pulling the trigger instead of squeezing it, and that combined with the heat and sweat is probably what is causing the less than fortunate shooting. Do this test:
Make your pistol safe (obviously) and remove the magazine (make it front-heavy to increase your grip strength)
Cock the hammer
Place a fattish coin on the slide just behind the front sight, upright so that it will topple when you move the pistol
Aim at a target in a safe direction (I'm sorry, I'm very safety conscious when it comes to firearms), and squeeze the trigger as you would when shooting at a real target
If the coin falls off, you're doing it wrong. You should adjust your trigger pull so that it's still safe to carry the pistol, but not too heavy that is requires effort to squeeze off a shot. This effort
will affect the grip and twist the pistol to a certain direction, causing you to shoot inaccurately, constantly. Practice practice practice...

I was taught this method constantly when I was younger, and it was drilled into my head. Still, I get too little exercise to shoot with pinpoint accuracy constantly, and I usually get excited when the fourth or fifth bullet hits the same place, and this causes inaccuracy and idiotic shooting (literally moving from a constant 1"-3" grouping at 10 yards to a m-m-m-mammoth 5"+ grouping).
