Hello, Mr. Moderator!
You might check into the availability of that .17 Convertible. I've been hearing rumors that there were problems with the .17M2 cylinder. Supposedly the factory has suspended the shipping of the Convertible model. Like I said, rumors- you know the Internet...
I would suggest either of the following:
1) A Single-Six, stainless being my personal preference. I have two, a 4-5/8" and a 9-1/2", both with adjustable sights. The short barrel is a Lipsey's limited run from a couple of years ago. The long barrel is a "Star Model" from 1974, made with the .22 LR barrel only.
2) A S&W 617. I've owned the 6" 6-shot in the past, but it had to be sold for tuition money.
I currently have the 4" 10-shot and the 8-3/8" 10-shot. (Graduation has its benefits...
)
As you can see, I have a long/short barrel fetish. I usually pass on the medium length barrels.
Happy shopping!!!
