I’m not currently carrying a nine (alternating between Colt Mustang .380ACP and Para LDA Carry .45). I have carried one in the past (most recently, a Kahr PM9) and may do so again, if I find the right combination (e.g., more capacity than the PM9).
My experience with Glock is limited to shooting my BIL’s LEO hand-me-down .40S&W. My accuracy with it was approximately Minute of Barn and, as a result, I haven’t experimented further.
I do have the following experience to offer related to ported barrels (as usual, my experience only, YMMV):
I once owned a Springer Ultra Compact that came factory-ported (V10 model).
1.) I couldn't discern any difference in recoil between it and any other lightweight .45ACP I own, and I have more than the two.
2.) I fired it during the day, at twilight, and at night. The flash was impressive at night but I did not appear to be, in any way, "blinded". That, for me, doesn't seem to be a valid issue.
3.) I was skeptical that the ports would pass enough gas to do damage when fired in retention so I set up a sheet of copy paper in a frame. I fired the pistol a measured six inches below the paper not expecting even scorch marks. The upward blast from the ports blew the paper apart, burned it and blew it out of the frame. Not exactly scientific, but I quit carrying the ported pistol.
I have posted this before on TFL and have had responses which:
a) criticized my “study” for being unscientific (which, as a scientist, I readily admitted up front) and
b) denied that the exhaust from the ports has any power to harm a shooter
So, my opinion may not be representative. I still won’t carry a ported gun for SD if I can avoid it.
And, I still have eyebrows
.
Best,
Will
