I've shot production and limited. Mostly production though. I guess that's a lie about my Glock- it does have some old, fading night sights (bought it used)- and am considering replacing with some iron sights - Dawson or Heine or the like. Otherwise its stock. I wanted time on a "regular" gun.
I haven't shot any IDPA- would like to, but they don't have it up here.
