I've always liked the 469 and its stainless cousin the 669. Years ago I bought my father, an avowed Colt revolver man, a LNIB 669.
He had told me he wanted a low maintenance, high capacity 9mm semi auto. It had to be concealable as he is a retired police officer and carried all the time.
We went to the local dealer and he picked the 669. Kept it for decades as his only semi auto handgun. He recently gave it to me. Fine pistol. Finer man.
Having always liked the Devel custom chopped and channeled S&W 9mm guns and never having been able to afford one, I have wanted to pick up a 469. It reminds me of both the Asp and Devel guns.
I know a Captain who was over a plainclothes team who carried the 469 as his primary. He used it a few times and was well pleased with that gun.
I have seen different "variants" of the 469. IIRC there were some nickel ones made. Also I've seen some blue ones with ambi decockers. Some with Uncle Mikes grips, some with other rubber grips and two types of factory OEM vinyl grips. One type is shiny black, the other a flat finished dark gray black.
Not owning a 469, yet

, I can tell you of my experience with the stainless version, the 669. It is accurate and as reliable as my 3rd gen guns. It uses the 69XX series mags too.
I advise you to buy it, shoot it, love it. If a 469 crosses my path when I have gun money, I sure will. Hope this helps! Regards 18DAI
As to value, I'd estimate $550 to $575 for LNIB with box docs and two mags. Maybe $475 to $500 for used in very good condition.
