I've liked a few posts above, without necessarily having had my own experience to confirm them.
I once owned a Model 41, S/N 90919. If I had had any actual intelligence, I still would. I have had a few Rugers, including a MkI suitable for bullseye matches with only a Clark trigger installed by Johnny Johnson. I now have a Ruger MkII Stainless probably unmodified, a Colt Woodsman Match Target, a 4" Huntsman and a 6" Challenger. My cataracts now prevent me from making reliable pronouncements on the accuracy of anything I own, although I do remember that the Challenger (probably a retired Marine Corps purchase) gave me no problems in earlier bullseye shooting.
I do concur with the recommendations of the Ruger MkII. I got mine for $100, and the only drawback was a trigger with an absolutely ridiculous amount of takeup. Once I got used to this, however, the trigger did not present any other problems, and was actually quite usable,
The Colts were all OK, each having a trigger that one would expect on a gun of its place in the hierarchy of price and intended use. However, the price of extra magazines today renders all Colt .22s impractical for most people.
Ruger? Furrin?
Good luck!
