I’m a big .32 fan, but bigger holes leak more, and give a better chance of clipping something important inside.
So, IMHO, a .38 is the better choice if caliber only is considered, whether it 5 vs or vice versa.
But the thread is about .32 caliber effectiveness.
It’s better than a sharp stick, no doubt, and I, as have millions of others, carried one, and will likely do so again.
Picking nits with people, and inserting info that has not been mentioned previously, simply to cloud the issue, side tracks threads, and convinces no one of anything.
