charls,

Here's my experience. Have had a 687 SPII Sporting (30" bbls) for 5 years. Fired nearly 10,000 rounds through it. Not one hiccup from it. Perfect record. Two trips to Cordoba for high volume doves averaging a shell every 14 seconds for three hours at a time. Probably the last bird gun that I would part with voluntarily, out of twenty or more.
I unhesitatingly recommend it.

May God bless America and those who defend her.
