I owned a 2206 6 inch bbl pistol that I had bought new. It had adjustable sights and I ordered a set of walnut grips with thumbrest for it from Smith & Wesson. I wanted to like the pistol, and it has some unique qualities that are kind of nice, one of which is the take down process, you can strip it down for cleaning without any tools. One word of caution, the owner's manual states that you should not dry-fire the pistol, and they mean it. One dry-fire can break the firing pin. I can vouch for this from my experience.
I have no doubt but what the pistol is capable of very good accuracy, but for me a pistol is only as accurate as I can shoot it, and I had other pistols, my bull bbl target Ruger MKII pistols and model 41 Smith & Wesson for example that I could shoot better. The 2206 kind of has a full lug bbl, the lug happens to be on top, but the barrel is fairly slim and it has a flippy feel in my hand. The trigger pull wasn't bad, it just wasn't nearly as good as my model 41 or my Rugers with Volquartsen internals. I could shoot my model 41 or my MKII Rugers better. I fairly quickly sold my 2206.
