Blowback operated pistols are notoriously hard to jerk the slide back on especially as the cartridge power level rises. So the breach can unlock after firing. The slide won't move back unless the barrel lugs move down and out of the way. For guns that do this sort of thing: The slide forms the rear of the chamber, holding the cartridge in place. When you fire the gun, pressure builds up, but since the cartridge can not move back, the only way out for the pressure is forward, taking the bullet with it.
Keeping the chamber sealed until the bullet leaves the barrel makes much more efficient use of the pressure from the powder. The barrel is locked together with the slide by some sort of mechanical means, the material you asked if we could shave off. But if we shaved it off, the slide and the shell would be free to pop out of the chamber when you fired a round, lowering the efficiency of the charge. It often does this by lowering the rear of the barrel, disengaging the edge on the chamber, or some internal teeth as on a After they disengage, the slide can continue moving rearward, with the extractor pulling the shell with it as it goes.
It will eventually slide past the ejector, smacking the shell out of the gun. As it continues rearward, compressing the recoil spring all the while, the slide cocks the hammer or its equivalent , hits the limit of its rearward travel, and starts moving forward again, stripping a new round from the magazine and pushing it up the conveniently tilted feed ramp into the chamber.
Still moving forward, the slide hits the back of the chamber, pushes the barrel forward, and re-engages its kinematic lock with the barrel. You are now in battery again. Sorry, I got carried away up there.
Basically the barrel tilts to disengage from the slide. Why is it engaged with the slide in the first place? To seal the chamber until the bullet has left the barrel. Why tilt? Because it's the simplest way to engage and disengage two parts. An alternative would be to have them both slide freely unless some kind of locking pin is retracted or whatever. That gets complicated and weak. That was very helpful! You would primarily use a ported barrel when you want to benefit from more accurate, quick shots.
To many, being able to hit a threat several times quickly is paramount for self-defense, so it just makes sense. That said, it may reduce the amount of recoil a shooter perceives , making shooting more comfortable in the process.
If a muzzle brake is attached to a pistol without a ported barrel, its added weight will also help to mitigate some recoil. A ported barrel may be appropriate if you carry an exceptionally high power pistol for self-defense the kind that some argue is better suited for a bear than a mugger. If you are just looking to enjoy casual fast shooting at the range, there is little downside to one as well.
But some of its side effects may hinder your ability defend yourself with your handgun. The hot propellant gases vented upward by a ported barrel are … well, hot. This matters in the nighttime. If you have ever had your photo taken with a flash camera in a dark room, you know how disorienting that can be. That is why a ported barrel can greatly impact your ability to fire accurate follow-up shots in the dark. A situation where you are forced to draw your weapon is an unpredictable one.
You may have to fire your weapon in an unusual position. Porting can direct greater report back at the shooter, potentially making firing more deafening in addition to blinding. If what you want most is to shoot really fast, then you will like how a ported barrel helps your aim stay on target. Compromising some performance in other areas could prove well worth it. That said, it takes training to really understand how to avoid injuring yourself with a ported barrel during a physical altercation.
If you would use your everyday carry during the nighttime, and you very well might, then the potentially blinding flash created by a ported barrel will do you a great disservice.
We hope you enjoyed this little report on the ported barrel. For our next feature, we are going to drink a barrel of port and tell you what happens. What is a Ported Barrel?
