I've been very impressed by many of the compact and micro models out these days. We - as shooters - imposed this unrealistic expectation of accuracy for such tiny firearms, but the industry has delivered. My wife's LCP is one of the most accurate (non-custom) pistols we own, for no apparent reason - just good design.

150yrs ago, the "belly guns" of the day in these size classes were terribly inaccurate and the triggers in them were horrid, but long range accuracy and silky, light operation wasn't needed or expected - hence "belly gun." It's amazing what these things can do now.
