Try this with a 9.3 - Hint: they don't make 0.366" dia pistol bullets.
9mm Makarov is .365". It is close enough to shoot well in my 9.3 bore. Moreover, one can always seat a Mak JHP backwards if the 9.3 bore is a little too generous. The HP becomes a miniball type skirt. .366 meplat is a wicked wad cutter. May not feed from the magazine though.
