The type of competition you pursue will define the type of pistol you may and may not shoot with, at least to some degree.
NRA bullseye shooting, for example, imposes a .22 caliber barrel length of about 7.5 inches, but accepts scopes of all types, as I recall, whereas Olympic shooting limits barrel length to 6 inches and excludes scopes.
It would definitely be worth your while to start hanging out at:

Personally, I've been an NRA bullseye shooter for 30-odd years, and have always favored High Standards. That said™, all my High Standards are tired and getting fragile. I've been shooting a pre-agreement Smith & Wesson model 41 the past few years. Out of the box, it was a dog, but with a bit of work, it became a pretty good shooter; its trigger, however, doesn't compare well to those in my best High Standards. I have a Browning Medalist with a trigger from heaven; unfortunately, I can't hang onto it, since the stocks were designed for a significantly larger hand than mine.
There are no more top quality American match .22 caliber pistols on the market, sad to say. If and/or when I buy another match pistol, it will have to be a Walther, Pardini, Benelli, or other European import: all horrendously expensive, some more reliable than others.
A friend recently bought a top of the line Walther, and is very happy with it. I'm doing most of my practice shooting these days with a Kimber model 1911 with a Kimber .22 slide and a hot-rodded Ruger Mark II. I'm trying to save wear and tear on the model 41. If I could coax the last of the creep out of the Kimber's trigger, it would be the best of the bunch.
No easy answers. Sorry.
