It would seem there is a slight velocity loss.  How much?

Is the loss worth the benefits (which i personally dont believe, for me)

I don't think that would be of much benefit.   I could be wrong.

Porting cost about 50-60 fps vs not ported, Glock 23 vs 23C
Noticeable reduction in muzzle flip.
In before anyone post about blinding flash, different ammo has different flash, some less than others.

Probably lose about 50 fps.  Increased flash and noise.  Reduced muzzle rise.

Have you ever shot a ported gun from a retention position?
Try it some time I am sure you will understand why ported carry guns are a bad idea.

The experts here say to tilt the gun sideways so the ports don't blast your eyes and blind you after the first shot.

Having shot a G20C from retention, it is not quite "blinding" but I would certainly put it in the "pocket sand" category. It sucks. A lot. But it's not as eye-ball melting as some think.
Flash at night at normal shooting position is definitely not blinding like some people say, either. Yes, you can see the big flaming V for a micro-second, but it's not like you're Mr. Magoo after one shot.

I would probably not port a sub compact unless recoil was a large enough concern (elderly/female/disabled/etc) to deal with the draw backs. While the drawbacks are slight, it is still a compromise.

Done it plenty of times w/ a Glock 19C.   Rotate it about 45 degrees and it's no big deal.   Haven't seen an accuracy difference at the distances where you shoot from retention.

I don't understand porting "regular" guns.

Is the recoil too much for people? Just shoot the damned things, you limp-wristed girlymen

It's not about recoil.  It's about muzzle flip.  With a sear on the back of it a 19C  it stays flat on full auto.  Try it without the ports.  The same effect makes it very easy to shoot fast and accurate on semi auto.  You still have the recoil but it comes straight back.

Having to remember to turn my gun 45 degree during an adrenaline dump situation seems like just one more thing that will be forgotten.

Shoot a ported pistol then non-ported version of the same (Glock 23C/23) with a shot timer & same ammo.
2nd shot times are quicker with the ported version, even when Glock 19/19C

Porting pistol barrels is obviously not a new development, so let me rephrase:  If the advantages outweighed the negatives, you'd see it a lot more.

I just switched to shooting all my pistols from retention the same way.   Worst case you get some hot gas up if you forget. It's not the end of the world.   I don't hear guys bitching about revolvers from retention, and they have a danger zone to the sides.   I suspect it's one of those things that under an adrenaline dump you won't even notice.

The reason you don't see it more is because it costs money.  Guys will spend crazy money on guns then cheap out on accessories, ammo, or getting it ported.  I have a S&W 642 with a ported barrel.  I bought it used and it was already ported.  It helps with follow up shots.

You are supposed to pin the grip to your body when shooting from retention.
45* seems stupid.

Getting it ported?  If there was demand, manufacturers would be offering it.

Worst case just shoot it normally.  It works.  I've done it.   There's just some hot gas coming up.   I'll take the minor problems w/ retention for the advantages when shooting normally.
