52's had lapped slides and frames and hand fit barrels and bushings. They were high end bullseye pistols with excellent single action only triggers. They are a delight to shoot, but your ammo options are limited to 38 mid-range wadcutters only. And mags are long discontinued from the factory and hard to find.
Yet if you are into them, they are so much fun to shoot with clear adjustable irons sights, a crisp trigger, mild recoil, and superb accuracy.
