What's the most fun you've had from a pistol?

[short-carabine]

Johnny English night many years ago. Barn pitch dark flashing lights and a series of targets to move between and shoot. It was quite fun but an outside observer would probably have had us locked up. The thunderflash at the end was ........well.....loud.

Sounds fun! Was this a timed "competition"? Which pistol did you use for it?
