My 624 has a recall for a bad cylinder. I received this when my father passed away in 1987. Been looking at the recall issue for awhile and finally emailed S&W and sure enough, it is on the recall list. I am going to call them Tuesday and see what my options are. This is more of an heirloom than an actual shooter. I was going to pass this on to one of my kids but don't want them shooting a heavier load and having the cylinder crack. It has only had maybe two boxes of shells shot through it and no problems. Does anyone have any info on this?
