shooting games and plenty more
I suggest shooting 'games' teach gun-handling skills that enhance one's safety skills.
And technical shooting skills like grip or draw or reload.
And what actually doesn't work, whether it be gear, ammo, or attachments.
And confidence.
And the ability (hopefully) to act, with a handgun, while exposed to pressure (the amount is personal, just like during real-life events).
Confidence learned playing the 'games' is what I consider the grail.
So I use the guns I own, modified if needed but only for social event use, worn in social gear.
Except I use alotta weenie ammo (not-so-oddly, if I am happy with the reliable function and demonstrated accuracy, often that 'game' ammo is still in the gun for social wear).
It's about being involved, competing, learning, and camaraderie.
And a burning desire to win (no, I don't, well actually once --8-rd mags, 45 Minor-- , but I try....)
