Chatgpt and 1911

[midatlantic]

So I asked Chatgpt whether the barrel of a M1911 was supposed to strike the vertical or horizontal impact surfaces on recoil.

 

here’s the answer:

 

During firing and recoil, the barrel of an M1911 pistol is not supposed to strike either the horizontal or vertical impact surface of the frame.

The M1911 pistol operates on a short recoil system, where the barrel and slide initially move together, and then the barrel tilts downward, unlocking from the slide and moving rearward independently. As the slide continues moving rearward, it compresses the recoil spring and ejects the spent cartridge.

During the rearward movement of the barrel, it should not make contact with any surface of the frame, including the horizontal or vertical impact surface. The barrel is designed to move independently of the frame during the initial stages of recoil, tilting downward to unlock from the slide and continuing its rearward movement due to its own inertia.

As the slide moves back into battery under the force of the recoil spring, the barrel tilts upward and locks back into place with the slide, ready for the next shot. At no point during this process should the barrel strike any surface of the frame, including the horizontal or vertical impact surface. Any contact between the barrel and the frame could cause damage to the firearm and affect its accuracy and reliability.

It should have been published on April 1st.

Here's the correct answer.........

It's amazing the number of guns coming from manufacturers without a VIS (vertical impact surface) cut. This cut is where the barrel feet impact during link down and recoil. The cut insures that top or most rigid portion of the barrel feet take the impact instead of the lower area. Cutting it is not difficult and can be done without a refinish.

Not sure how that makes any sense either.  If the barrel is already installed and not contacting the VIS, removing material from the VIS isn't going to fix the problem.  Maybe what they mean is to add a relief cut so the lower portion of the lugs don't contact the frame.  But that may or may not fix the problem.  Also, that's only relevant for non-ramped barrels because ramped barrel cuts don't have a relief.

Understand a ramped barrel does not need a relief/VIS............

 

My answer was with regards to the OP's "answer" he posted:

That statement is not ENTIRELY correct.

There are plenty of sources online that explain how to do this correctly.  Clearly Chatgpt isn't one of them.

Agree!

Yep what I thought so interesting is how definitive it sounded. Like a command! This is how it works….wonder what else it’s wrong about…

IMO, it's probably a quote that somebody read or misinterpreted in some way.

 

Straight from the 1911 Timing Test Kit courtesy of Wil Scheumann:

 

Quote

Before a 1911 is fired, the slide is forward and the barrel is locked to the slide via the meshing
of the upper lugs on the barrel into the matching grooves in the slide. The barrel is hooked to the
frame via a link, the bottom end of which is connected to the slide stop pin. The link is vertical when
the slide and barrel are forward. When the gun is fired, the slide and barrel begin moving rearward
together. As the barrel moves rearward, the link rotates about the slide stop pin and starts pulling
the barrel down, thereby beginning the unlocking of the barrel from the slide. After the link pulls the
barrel downward sufficiently, the barrel becomes completely unlocked from the slide. Then the back
of the lower lugs on the barrel will hit the impact surface in the frame, which will stop the barrel's
rearward motion, and combined with the link, the barrel's downward motion. The slide freely
continues rearward to complete the ejection of the fired case and then moves forward to load the
next round into the barrel.

HTHs

People rave about ChatGPT generating code too, but unless it can swipe the exact code from somewhere, what it comes up with looks good but is often spectacularly incorrect.

ChatGPT can't generate anything but extremely simple code and even that will not run without a human fixing it first.  It's a lot of hype...
