    Compensated uses an additional item at the end of the barrel that does vent gas as you mention. But it also uses added mass/weight to help with those as well.

    Glock has had ported guns with a 'P' as well. Eventually, practice guns like the 22P and 23P kept the 'P', and ported guns use just the 'C'.

    The ports on an OEM length barrel are kind of far back. Trust me, the effects of the escaping gases begin pushing downward on the muzzle after the bullet passes the ports but also before it leave the end of the barrel. It still does after the bullet is midair, but the intense compensation is bullet between the ports and end of the barrel.

    Ports on an extended barrel are much like a compensator or muzzle brake. The bullet is basically leaving the barrel when the gases hit the vents. The gas is under extreme pressure, so it's going to vent in any direction it can after the bullet passes. If some of the gas is directed straight up, it can only push down on the muzzle, even after the bullet passes. Remember that the bullet never touches a threaded brake or compensator. It's why ports at the end of the extended barrel work the same way.

    'Compensated' uses some kind of device that creates a negative effect of recoil and/or muzzle flip through the redirection of some of the escaping, pressuring gas. If it's a ported, OEM length barrel, it is still 'compensated'. There is no additional weight with an OEM length ported barrel like there is with a threaded compensator or brake.

    I had to come back to this forum after I came across some simple info from Glock's site. As it turns out, "Compensated" does not mean it's a device attached to the gun. There are devices called "Compensators" but that alone doesn't determine the definition of the word "Compensated" as it applies to a Glock. If a Glock pistol has a ported slide and barrel, then it is a compensated Glock. If it has an aftermarket device for reducing recoil, then it's also a compensated Glock. I appreciate all the responses I got, for sure. Apparently this subject has been debated before, or at the least has been a source of confusion or disagreement, or misunderstanding.

    Apparently Glock considers it's pistols to be "Compensated" if the slide and barrel are ported. No aftermarket attached device necessary to achieve that status. The act of "compensation" happens with the recoil/muzzle blast is reduced because of the porting.

    I don't know who all really cares about this string of posts anymore, but I think I came across the simplest of answers, where GLOCK is concerned, anyway. A Glock with a ported barrel and slide, IS a compensated pistol. But then so is a Glock that only has a device of some kind attached to the barrel, for the purpose of reducing muzzle blast.

    I would rely on the universally defined definition of "compensated" that was intoduced in the 1970's for competition use than I would a sole firearm manufacturer who decided to incorrectly define decades later what was already universally defined as porting.

    Where exactly are you getting this "universally defined" info? I'm finding similar info between Glock, S&W, Springfield, etc as to what porting and compensation is. "Compensated" was apparently orginally called "Muzzle breaking" and goes much further back than the 70s, and was never just about competition. It's military in origin from what I see. But there does't appear to be any one single universally recognized definition, from what I can see. I'm interested in the historical aspect of porting and compensating if you have links beyond what I've found. Thanks.

    A good way to remember the correct spelling is that a muzzle "Brake" is so named because it's like the brakes in your car that slows your car down. And a muzzle brake slows down the rearward motion of your muzzle.

    Also muzzle brakes are more effective than ports because they add a larger chamber to direct combustion gasses than is possible with just the thickness of the barrel. And a compensator is more like a muzzle brake than it is a muzzle port.

    In the end, it all comes down to this, no matter who builds the gun:
    1) gun with ported OEM length barrel and vented slide = compensated

    2) gun with extended length ported barrel and no slide vents = compensated

    3) gun with compensator attached to threaded barrel = compensated

    4) gun with muzzle brake on threaded barrel = compensated

    5) gun with dual duty compensator/brake = compensated.

    My Tracker .44 mag revolver has built in ports but the actual barrel end is just before the ports. It does not fall in any of the categories above. It is also 'compensated'. https://s3.amazonaws.com/mgm-conten...994_05_taurus_44_mag_tracker_revolver_640.jpg

    No, still 2 different things. Porting works while the bullet is still in the barrel, and the comp works after the bullet leaves the barrel.

    Both what you describe are ultimately 'compensated'. Each device is a little different but they both work to apply force against an already existing force to reduce trauma. It's not that hard to understand, my friend. ;)

    Got to go with the way Harold broke it down. Also, it seems this has become somewhat of an issue of the mechanical/grammar usage of the words. All those possible setups amount to a gun being compensated. "Porting" is not an action that happens when a gun is fired. "Porting" is the act of creating the ports, either on the barrel, the slide, or both. A "Ported" barrel contributes to the action of compensation - that act being the reduction of a force.

    Terminology is often just something generally agreed to within a community, a lot less black and white than most would want. Glock was the first I recall that kind of stepped outside the lines bluring what others had tried to draw a clear difference between.

    **WARNING POSSIBLE SEIZURE INDUCING HAZZARD BELOW**

    Webster’s dictionary clearly defines “clip” as an acceptable synonym for “magazine“.

    3BD3AEF9-548A-45CD-8241-2923071EEABD.jpeg LOL, well first off does Glock still Port their barrels?

    Magnaporting was doing business in the 70’s, they did a Ruger for me, they are still around today. Glock was not making pistols in the 70’s, in fact business was overseas and doing curtain rods.

    Glocks Misuse of words predominates.....Glock Perfection comes immediately to mind. The attempt to proclaim a 3-1/2 # trigger in their target model 34 was determined bogus and 4-1/2# nomeclature replaced the fib,
    after Competitors made the same false claims.


    You can fight the fan bois theme, and be a good little customer, it does make for entertainment. I’ll leave you with a updated Ruger which has been ported.

    Not everything in German translates exactly to English correctly, nor does everything in English come out right. A clip is not a magazine. A clip is a device to load a magazine with, but a magazine is what loads the gun. Moon clips load the magazine (cylinder) on a revolver, stripper clips load the magazine on auto pistols and auto rifles.

    Early compensator on 1911 Open Division gun, long before Glock porting. I still have my original Pro Point.
