While looking around for a compact hi-cap auto-loader, I have come across several second generation 469s and 669s for bargain prices. I have also seen a lot of police trade in 6906s and 6946s, though these are more in the Glock and M&P9c price range. I was wondering if there are any big advantages of a third generation pistol over the second generation guns. From what I have read so far, the first generation Smiths had issues, and the third generation are darn near perfect, but not much is said about the second gens.
