In my area, the nickel 19 with all of the accessories listed is a pretty good deal, a better deal than the price on the 28. The 28's do seem to be climbing in price though....

The 28 cannot be beat in terms of durability, not that you will destroy the 19 shooting mags out of the if you do your part in not abusing it.

I have a 28-2 with 6.5", and a pair of 19-3's with 4" and 6". Given the choice, I myself would go for the 19.. I don't have a nickel Smith yet and would like to get one at some point.
