When the rule changes were put out for IDPA members to review, it was seriously considered allowing the seven and eight shot revolvers to compete at full capacity in ESR. That set up a hue and cry from all the folks shooting moonclip guns. "It's not fair!" Of course, it was fair when they were shooting against folks using rimmed cartridges, 158 grain bullets and speedloaders. FWIW, I think they should have been allowed to compete at capacity.
You cannot reload with seven rounds, unless you want to get a procedural. The rules are pretty specific that you can load to a maximum of six rounds.
Grump, Ken Hackathorne made a statement that "Five inch N Frame revolvers were not practically concealable." (That's a paraphrase btw.) I personally believe the reason revolvers were limited to a 4" maximum barrel length was to cut down on the number of S&W M625's being used. Yes, you can use a six inch gun for nightsand/home defense, but would most of us revolver types actually try to carry one on the street? Part of the idea and guiding principle of IDPA is for CCW purposes. Let's keep it all in perspective.
