Hello Wood,
I have a 5906 with-as of last weekend-a little over 4,000 rounds of hollowpoint, range ammo, reloads and various other brands through it without a single malfunction of any kind.
Never thought I'd find a classic, steel auto that would "Out Glock a Glock," but I have found exactly that. I don't get attached to guns very often, but when I do, it's a S&W 5906.
Good choice. Replace the recoil and magazine springs if and when needed, other than that, you're set.
Best,
Heekma
