The first question you have to ask yourself is "How do I use the weapon?" of maybe "What do I really expect from it?" Hint: the model 52 was intended to group within a pistol X ring at 50 yards in competition. Whether or not you can is another story.
If you're someone who demands accuracy, a bushing that is a tight fit to both slide and barrel is part-but only part- of maximizing accuracy. Quite frankly, the fit of the barrel to the slide is the most important part of the process since the sights are attached to the slide. However, requiring a wrench to remove the bushing can be a really bad thing under field conditions. If you lose the wrench, you're SOL for field stripping. You're also compromising reliability in unfavorable environmental conditions like dust, mud and fouling from extensive firing without cleaning/lack of lubrication.
Various other designs have eliminated the barrel bushing, at least as a part of weapon disassembly. So long as the barrel has reasonable tolerances at the breech end, spring tension will cause the muzzle to return to an reasonably repeatable position for acceptable (if not outstanding) accuracy.
