I rotate two ported J-frame revolvers through my normal street guns. I trust them, I've tested them to my satisfaction as regards throwing debris up and into my eyes. They are both keepers - the porting allows me to run comfortably, 38 +P ammo, and i one 38 +P+. Both are rated 357 which they will never seen. But neither are they confined to 38 Special only.
I shot the life out of a ported P365. I wanted to like it. I disliked the recoil impulse. I put a Wilson frame on it. I sold it.
The next ported auto I buy might do it for me.
The two revolvers make a noticeable difference in handling, not so much so in terms of noise. Yes, they are both louder than matching non-ported guns. I don't relish using one in tight confines - read that to be a bathroom cubicle perhaps. But then again, I don't relish the thought of ANY gun in there.
Your mileage may vary. That's my latest round of decisions.
