Next company comes along that produces a fullsize gun .1 oz lighter than 5.7
The difference is not minimal; the difference is dramatic. A loaded Five-seveN is substantially lighter than any loaded full-size pistol of your choice.
This is not what 65% of LEO are saying right now
No, because the Glock is an old pistol chambered in a
number of different calibers; most of which are extremely old. The 5.7x28mm is a relatively new caliber and the Five-seveN is a relatively new pistol. It's in use in over 40 countries within only 10 years of its creation.
Thousands of gun owners port their firearms for serious use, including defense situations.
That is pure fiction. If you look at the collective experience on virtually any gun forum, in virtually any discussion on porting for serious use, the vast majority would
never use a ported pistol as a CCW. See, for example:

Quote: "As said above, gasses and debris could be painful and/or blinding when shooting from close-in retention position."

Quote: "Ported guns IMHO are good only for IPSC competition, shooting a ported gun or with the weapon close to your body canblind you in the dark and burn you badly in close retention type shooting, so no porting needed for a carry gun."

Quote: "Do not carry a ported gun for CCW."

Quote: "For CCW use... do NOT get a ported/compensated pistol.
IF you ever have to fire from any kind of retention position, you will be showering your face/neck with hot gases, possibly shaved lead/copper/other metals from the passage of the bullet itself.
I watched a guy in Gabe's CRG-1 class doing the 1yard and closer shooting drills with a compensated Glock. After a couple go's, Gabe got the guy another pistol so he could finish the drills. This guys face was NOT pretty -- had nicks and cuts all over it -- after firing as few as 3-10 rounds (my estimate)."

Quote: "A test was done where a shirt was draped over the ports on a Glock (simulating a retention shooting). The shirt was immediately started on fire. I don't beleive porting helps that much on an auto pistol to put up with the disadvantages."
---
Quote: "Sorry to be so blunt but for anything but competition/injured folks,Ported pistols are a poor choice for personal defense.
I once saw a guy(who will remain nameless) doing a weapon retention demonstration,get a nice piece of his hand chewed up by the hot,fast moving gas coming out of a ported pistol.
I have seen others get crud in the eye orbit when doing close range/pectoral index firing with ported pistols,as well as tearing shirts and superficial burns.
The extra blast,which is directly in front of your line of sight,doesnt help your night vision at all.
If you are relatively healthy and strong(My 84 year old Grandfather can still shoot a 1911,just not as fast) leave the ported pistols for plinking and gaming.
The negatives outweigh the positives using comp's on defensive pistiols."

Quote: "If you add magna porting to the barrel the perceived recoil will be less, but then you add the issue of hot gases being directed upward this can be a problem for your vision if your gun is needed in low light conditions. In addition, the revolver is a niche gun that is perfect for close in work. Having those gases directed upward could be a problem if the revolver is being fired in a close , high ready position or from inside a coat pocket."

Quote: "Porting the 340PD isn't worth the effort - given the extremely light weight, porting doesn't make that much difference in muzzle flip, and nearly no reduction in recoil impulse. There is a big increase in perceived muzzle blast, however.
Don't for a minute believe that it will work magic - if it's a handful for you now, it will still be after porting."

Quote: "I'll just chime in to support what was said above. I've witnessed shooters on the range have real issues with ported guns when firing from retention positions such as high compressed ready or during CQB shooting. Even with safety glasses on, I've seen folks have to leave the range for an eye-wash station to try to wash out the particulates that found their way up and behind the glasses. Running into a situation such as that in a real lethal force incident could be detrimental to your health."

Quote: "I would agree with Thunder, that for larger, very powerful guns, they help cut recoil. But for your defensive calibers such as 9MM, .38, .357, .40, .45, .45GAP etc., more benefit would be gotten from proper training on how to handle and deal with recoil management, and other aspects as grip, follow through, trigger reset, and stance.
I took an instructors course a few years ago with deputies from a Washington department that allowed ported guns. One deputy had a ported model of a Glock .40, the others non-ported models. Using the same ammo, the ported gun not only had more flash, but lots of debris thrown out upwards at the ports. The deputy showed up on the third day with the non ported model. I fired both models and found no difference in handling qualities. Depending on the ammo you use, there may be less flash with todays use of low flash powders."

Quote: "The reduction in night vision is only part of the equation. Those who tried shooting from the Retention Position (Position 2) for Close Quarters usually are not happy after they've done it once. Many students after they've done it once will refuse to do it again. Well that could be a problem in an ugly close encounter. We want to train the way we may have to fight and we don't need any more reasons or excuses not to do something in training."

Quote: "If you are buying this pistol for a ccw/defense I would recomend not getting the ported barrel. The flash at night will impair your vision."
---
Quote: "ported barrels are great for the range. ported barrels are bad for carry."
---
Quote: "Ported barrels are serious range and competition equipment and freakin' terrible options as carry guns. There are a variety of reasons this is true but just try letting go with a round with the barrel close to your belly or chest as in a close quarters situation where the factor of weapon retention becomes greatly magnified and it will become crystal clear."

Quote: "So there I was..... practicing some SD drills at dusk last night. First problem, the muzzle flash from the porting blinded me worse than from my non-ported model. That really wasn't a surprise I guess. However, the second problem arose when I was doing some hip shooting. Thank God I was wearing my shooting glasses, because this little beast was blowing powder and shards of who-knows-what out of that porting and directly into my face.
I had never given it consideration before, but why would a manufacturer even offer this as an option in their line of self defense guns. This feature is just plain hazardous to the user. When the BG is close the last thing I want to have to worry about is if I'm going to lose my vision if I pull the trigger."

Quote: "Porting is just fine if you like setting your OWN clothes on fire/powder burns etc.
I'd rather throw all that hot gas DOWNRANGE at wahtever I'm shooting at."
