629 Burrs on Cylinder Notches

[Duskykiller]

Had this 629-1 for a few days. Have put about 200 rounds of mild 44 magnum reloads through it. Shoots great accuracy is outstanding. But when I cleaned it today I noticed this burr in the cylinder notch. I don' t believe it was there when I bought it. What would cause this notch to get a burr like this? What is the fix? Thanks for looking. The last picture of of another notch without a burr.

If you'r one of those guys that like to spin the cylinder and give er a flip of the wrist to flip the cylinder back into the frame, that will do it for sure. Looks like it was smackin the cylinder stop with some force. If your NOT one of those guys, looks like a slight timing issue.....

Please please don't tell us you do the "gangsta flip."
No one does that..outside of Hollyweird. Right?

How does the cylinder stop look? Take a look.
If you develop a burr on the CS it can scratch a nice pronounced turn line into your cylinder. The CS may need a light polish. If you do it...be very careful not to change the dimensions of the CS! Just polish it up.

Are you in the habit of cocking the hammer back into single action very slowly?
Some revolvers may not lock up immediately if the cylinder is dragging slightly and a very slow cocking motion is used.

If you don't find issue with anything on your 629, then...
Check the timing.

No gangster flipping has been done. Most of the shooting is slow single action with some double action just for fun. I see nothing wrong with the revolver. But I am no expert. Will Smith Wesson still work on q 629-1?

The "some double action just for fun" could have done it.... if you were repeatedly trying to pull a "jerry Miculek" by rapidly shooting off 6 rounds as fast as you could pull the trigger, that sends that side of the cylinder notch slaming into the face of the cylinder stop/bolt and it will raise a burr.

The 629's were also the subject of a recall for cylinders made of sub-standard materials: 624/629 Recall Notice

If you send your gun in and it is found to be one that falls under the recall needing the cylinder replaced, you will not get it back. S&W no longer has any replacement cylinders for the older guns and will not ship an unsafe gun back to a customer.

If indeed a rapid fire DA stunt did the deed, all you have is cosmetic damage and lesson learned.

Being that it is a stainless steel gun... you could smooth that burr out with 400 wet/dry sandpaper and blend in the area with a scotchbrite pad. Plenty of posts on this forum about how to rejuvinate SS guns with the 3M pads.

There has been no rapid fire no cylinder flipping. Just easy slow shooting. Noting the burr today make no sense to me but it is there.

[Gunhacker]

Then that makes we wonder whether or not that was pre-existing and was not noticed during the excitement of acquiring it (been there, done that). 200 rds of "easy slow shooting" should not of been enough to raise a burr that pronounced... I'm with you, it makes no sense.

Serial number on this is AFB69XX this looks like it might be in the recall range.

One last guess...... Perhaps your bolt stop is hangin up and not snapping into the fully upright position in time ? Dried up caked grease, schmutz, etc...... Try this ................
Ensure the Revolver is unloaded, and hold it sideways in front of a light, and cycle the action. The bolt stop under the cylinder should pop up and be rubbing on the cylinder well before it comes to the notch. That way it can pop into the notch as soon as it appears. If it does not do this, perhaps it need a good cleaning to get rid of old dried lubricants.
