I have just started shooting IDPA this year, and have attended two matches so far. Great fun! I entered the first match with a Springfield 5" 1911, slightly customized, with iron sights. the second match, i used a Kimber Compact CDP. This weekend at the local gunshow, i ran into a HP Practical for $295!! I figure this would make a great gun for these types of competitions. Anyone else use these for IDPA? I also hear that the South African 17 round mags work really well in the MkIII's. I purchased 3, and hopefully they will arrive soon! I pick up the HP tomorrow.
