I'm looking at the IDPA equipment appendix. It appears to say that Carry Optics guns have to meet ESP standards. ESP standards seem to say the pistol can be no more than 6" tall. My CZ P07 is 6" from the top of the RMR to the bottom of the mag well with a stock 15-round magazine in it. On the other hand, the rules say "...except as it relates to sights..." So...does anyone know how the IDPA pistol box fit thing actually works with carry optics? I want to use extended 22-round mags. If I ignore the RMR and measure the P07 from the top of the slide to the bottom of my 22-round mags, the measurement is just a hair under six inches. So I'd like to think I'm good to go. Anyone know? Thanks!
