What competition? What I'd recommend for action shooting (IPSC, IDPA PPC etc) would be different than if the competion was NRA Bullseye. If you're shooting Cowboy matches or Highpower, then the recommendation would be different again
I see you're in NC. I am in Greensboro. Durham Pistol and Rifle Club holds a variety of matches. They have a website for info. The season is over but that will give you time to get ready. It's a good club and you don't have to be a member to compete. One thing you'll find out about competition shooting: though you may not be a good shot, you'll shoot with the some of the best in the world. And if you think you're a good shot, watching some of these veteran competitors is a humbling experience.
Get something with a longer barrel than self defense conceal pistols.
SA good, 5" barrel. Glock good too. Go to range. Fire from benchrest at 7 yd target. Adjust sight until hit bullseye with tight group. Make sure ammo functions 100%. Shoot different ammo brands until find the best for your pistol, accuracy and function.
Then ready. IDPA fun. IPSC not.
Good quick draw holster helps. Plus extra magazines loaded helps.
LOTS of NC people here...If ya live in Greensboro...I think that the Riverside Gun Club in Ramsuer have a Action Pistol Shoot at the beginning of each month..Maybe second sat. of each month I am not sure...It is a decent club but isnt on the same level of the Durham Pistol and Rifle club....Get yourself a G22 or G35 to shoot..Ya make major and they are fun guns to shoot...
