A 469 was my dream gun when I was in college in the mid-80s. Reality being what it was, I wound up with a 439.
I now own a 6946 (the stainless slide/alloy frame DAO 3rd Gen version with tritium sights) that I got from a friend, and I'm just pleased as punch with it. I love the fact that full-caps are cheap and plentiful (I carry with a flat-bottomed 12-round mag and I keep it on the nightstand with the 15-rounders in it.
I happened to be at the range with the 6946 and a friend's HK USP yesterday; my S&W was as accurate at 10 yds as the HK (one-hole 25-round group about 1.5" across) with cruddy generic ball ammo. Reliability has been flawless since I replaced the recoil spring (my friend shot the 6946 a lot, and for some reason stored it with the slide locked back).
But, as much as I like the 69-series guns, I don't see where you
need one, given your ownership of the Beretta and Kahr (and everything else). Still, as I know you know, it's not always about
need. FWIW, if I had the opportunity to buy a 469 from a friend, I would (and I've got an HK, the 6906, and all kinds of milsurp pistolas and revolvers) in a flash.
Let us know what you decide! (I wish I had a friend who wanted to sell me a 469!
