Someone buys an all steel or mostly steel gun a la CZ, Gen 3 Smith, Sig, 1911, etc to help mitigate felt recoil.
So why do so many people/companies lighten, port slides, and do cut outs on Glock 34 slides? "less mass rocketing back and forth between your hands" is what I hear. Explain this to me |

Explain this to me AFAIK, Glock uses the slide cutout so that the mass of the long slide guns is closer to the standard-length guns, allowing for similar performance/reliability without the need for different components. Plus, the plastic frames also help mitigate felt recoil because they flex more. More mass is generally a good thing in terms of felt recoil (I'd rather shoot my 91-oz S&W 500 mag than a 13-oz S&W scandium snubbie firing full-house .357 loads). Less mass is generally a good thing in terms of slide function and reliability. |

For steel frame guns, the extra weight in the frame reduces perceived recoil.
For steel slides, the theory is that less weight moving back and forth will disturb the sight picture less, and reduces perceived recoil and the "catch" at the back of the recoil stroke has less weight/inertia. With the Glock, and other guns with lower slides, the slide being closer to being in-line with the arm also reduces perceived recoil, since the gun recoils straight back, rather than rocking. ETA: The above poster from what I understand is also correct about the factory cuts on the longer Glock slides. The cutout reduces the weight to match that of the standard slide, so Glock can use the same recoil spring and assembly. |

So why do so many people/companies lighten, port slides, and do cut outs on Glock 34 slides? "less mass rocketing back and forth between your hands" is what I hear. Explain this to me Heavy guns (rifles, shotguns, pistols) mitigate felt recoil imparted by the Cartridge. Lightening the slide on a pistol reduces the reciprocating mass gaining you two things. 1. Faster cycling. 2. When the slide hits the rearmost stopping point, a lighter slide will cause less "Flip" because it has less momentum. a super heavy FRAME with a super light slide would be the lowest "felt" recoil. BUT when you lighten a slide you have to up the spring weight to counteract the faster movement of the slide and prevent rearward frame strikes that beat the gun to death, and you need the extra strength to overcome the loss of slide "momentum" that strips the round and locks the chamber..... and at some point you need too much spring for the caliber to cycle reliably and you short stroke. Basically you are getting into the race gun tweaking when you try to do these balances....

| There is a big difference between overall weight and reciprocating weight. Overall weight counteracts the force of the bullet and gases exiting the barrel making less recoil. Reciprocating weight (the slide moving back and forward) disrupts the sight picture. Ideally, you want more overall weight and less reciprocating weight. |

Explain this to me Mass helps reduce recoil. BUT moving mass will make if feel like more recoil (which is why 9mm ARs often feel like they are recoiling just as much - if not more - than .223 ARs). Lighten the moving mass - and increase the weight of fixed mass (say the frame) for best recoil reduction. Comprende? |

Do you want to fuck the skinny chick or the fat chick? Explain your answer using physics. More like trying to organize an efficient 3-way. Do you want 2 skinny chicks, 2 fat chicks, one skinny and one fat? Then there's position, fat chick on top or bottom? skinny but ugly goes on the outside, etc... However, if you really need to see the math...

Explain this to me More mass is less felt recoil. Fire a Remington 870 vs fire a single shot 12 gauge shotgun and get back to me on which hurt more. They port them because it mitigates muzzle flip by using a component of the burning gases to keep the muzzle down. |

Explain this to me E = .5mV^2 Same velocity (spring change) and lower mass = less energy |
