My old age pecluded me from posting right away and Moralem beat me to it.
I have one also but not on the recall. None the less, I researched quite a lot as a matter of interest and came to the conclusion that there seems to be two schools of thought on the recall issue.
The first is the reason for the recall, some say a bad batch of stainless steel that may compromise the integrity of the cylinder strength and possibly fail. The second is, and Mr. Roy Jinks the S&W Historian is used as a source, is that the chambers were inadvertently bored to 44 Mag case lengths.
In either case, there are a few reports where S&W did not return the gun because there are no SS replacement cylinders. You may be offered a comparable firearm and/or a credit in return. I have yet to see or hear of an incident where a 624 cylinder failed and was directly attributed to this recall issue. You must also consider the possibility of resale and disclosure.
For those that returned the guns and had the modification done, supposedly S&W simply marked the box with a red C in a circle but did not mark the gun.
My thoughts, like you,I never intended to shoot mine daily or with any high velocity loads. The over bored chamber issue can be easily checked by inserting a 44 Mag round in the chambers to check if fully seats. If marking the box only and not the gun after modification is the only indicator of a repair, the reason or procedure for the recall seems suspect.
I would choose to keep mine barring any absolute assurance of cylinder availability and return.
