If it did that, it was probably the effect of a ported barrel, rather than of the handgun design. Barrel porting is done as a recoil reduction measure, and is pretty effective, although it can have some negative consequences in low light firing.
a ported box is better i have tried a sealed as well as ported and the ported dilivers far more power
Depends on what application it was ported for and by what process.
a ported box will hit the lows better than a sealed box. and they will hit harder.. but a ported box will be louder.
