I shot my first club-level match a while ago. Minimal handgun experience, borrowed gun (a sweet CZ-75B) and equipment. We shot courses with steel plates and paper targets, and I did surprisingly well for myself. Landed a solid midfield in the final rating, although I blew two stages rather badly.
What I learned was not to underestimate myself, and to approach the whole thing with fun in mind. And that's what I had - lots of fun. So much fun that I am going to do this regularly, and maybe enter our domestic/provincial league at some stage. Pity our club only does the handgun shoot every 3 months, the other 2 are shotgun and rifle.
