SIG 2022 slide rattles

I mean, the slide is really loose on the frame. As in, shake it and it rattles. Every one I've touched is like this, and so I was wondering how accurate it was going to be, since I bought one in spite of the looseness.

The SIG forum discussions on this all said that the 2022 is an accurate pistol, since the barrel and the sights were all tightly attached to the slide at the moment of aiming and firing. That results in the looseness on the frame being a "don't care situation".

And that is exactly what I found. It is as accurate as any other service semi-auto.

So why does everybody make a big deal of needing the 1911 slide to be tight on the frame, to achieve good accuracy? Could that be due to the different means of getting the barrel to press up into the slide for lockup, meaning pivot link versus ramped surface?

Who thinks rattle-around-looseness may be über-reliable.

Because misnomers spread like wildfire in the firearm world and word of mouth becomes accepted fact.
 
Generally speaking, the consistent fit (lockup) of the barrel within the slide, which locks the barrel to the sights, is what matters with most guns. (On guns where you have a FRAME*-mounted sighting system, frame to slide fit would also be important.)

Slide to frame fit has always been a recognized sign of a well-gunsmithed 1911, but most experts won't claim that it really adds that much to a gun's accuracy, if other things are right and you USE THE SIGHTS.

IIRC according to “The Colt .45 Automatic” by Jerry Kuhnhausen, the slide to frame fit accounts for 15% of total accuracy.

The other factors are as follows:

Match grade barrel 10%
Bushing fit 20%
Headspace 10%
Rear barrel side play 20%
Vertical lock up 20%
Beyond reach 5%

So it is not the most important part of the equation but it certainly plays a part. I personally think that people overstate its importance. I personally believe that bushing, rear barrel side play and vertical lockup are the most important parts of the equation. Get those right and the pistol will out shoot most shooters.

I think people focus on slide to frame because they can see it and feel it and they understand it. The other factors not so much.

You are correct; howsomever...
(howsomever is a word in Texas :))
Door to frame fit has always been a recognized sign of a well-engineered automobile, but most experts won't claim that it really adds that much to a car's speed.

Most enthusiasts agree that both are very desirable, especially on the more expensive models. :D
