I can't address issues related to the S&W 659; but
I had a nickel model 459 that performed really well.
I haven't seen either in recent years; or since the
introduction of Glock's, H&K's, and SIG's.
For 9m/m Smith self-loader's, I have always liked
the old original, single stack model 39-2 better than
any of the other's. Just my thought's and opinion.
