Barrel link pin

[tomjerry1]

I've noticed that the pin for the barrel link is moving, should it be staked, or red Loctite?

Staked

Describe moving. 

[tomjerry1]

it's moving latterly, the frame is retaining it, can see marks from rubbing in the frame.

Well, the pin was moving on one side, had another an drove the pin out, and that was when I got two parts of the pin. Looks to me like a bad pin, rough on the inside and shiny and crisp on the outside.

If the gun broke the link pin in the barrel, it is not fit correctly.  Have somebody that knows what they're doing check it.

[jwhittin]

I agree, you should have the barrel fitting checked by a competent smith and let them install a new link pin.

There is a very simple to check if the link is too short. (main cause for broken link or link pin).

 

Remove the slide stop, then put the cross pin back in and leave the rest of the SS swinging.

 

Press the muzzle down on the floor and keep pressure on it, the SS should swing freely , if not the link is too short for the application.

 

NOTE : If your gun has full length dust cover, make sure only the barrel is pressed and not stopped by the dust cover.

I'll give that a try.

I checked that out, and the pin moves freely. I'm leaning towards a bad link pin, it broke cleanly around the circumference, and the middle looked cast and dark.

So you replaced the link? And followed Vma606 test?  As mentioned, it's important to make sure you maintain the pressure on the barrel.  And just to clarify, the slide stop pin should rotate (swing) around the pin axis with no side to side motion. Even if it doesn't rotate (swing) completely freely but you can easily rotate it with a gentle nudge that's okay too (the link increments are not that fine).  If this checks out then I would agree, it was probably a bad link pin.

Yes , I maintained pressure on the barrel, the pin rotated freely as you described.
