I am looking for input as to whether I should get a 9mm or 38acp. It will be a revolver and I have shot a light 38 but not a compact 9mm. Is there much difference between the 2 in regards to hand sting and kick? My 39 special hurts when I shoot, don't know if its b/c its so light or b/c its 38p ammo. Thanks for advice.
