The compensation is supposed to tone down the recoil a tad bit, i used to have a 23c and i couldnt tell any difference in recoil. The compensated version will be louder than the non compensated version and the ported barrel will produce a "V" shaped flame at night which can affect your night vision when using certain ammo. The 9mm doesnt recoil that much to begin with so its really just about personal preference __________________ Semper paratus.....virtute et armis |
