How stable? 'Splain yourself, Lucy!
You are aware that there will probably be differences in POI between 230gr and 185gr, aren't you.
And if you are looking for IDPA-style action, drop by Dominion Shooting Range on Monday nights around 6PM. It's not "official" official IDPA with boxes and calculators and lists of not-approved holsters, but good practical shooting. (There! hlh does not have to do his commercial now. 8>) )
