I just got a used 6.5" blued convertible a few months ago. It's a fun range gun which is all I use it for.
Some things to think about...
- Recoil is almost non-existent with 22LR, but there is a little bit with the 22WMR.
- The longer barrel might improve accuracy, but it also adds weight. Will this be carried at all?... longer barrel might be less comfortable for carry.
- The SS might be heavier than the blued. SS won't rust -- but if you're taking good care of it and don't live on the coast then it really doesn't matter. If you're buying new, I don't think the blued come with wood grips anymore (or least I haven't seen any) if that's important to you. And, then there's personal preference... which one looks nicer to you -- SS or blued?
- Another thing to think about... adjustable sights. Some have them, some don't. Mine is non-adjustable, but it's spot on.
Not a lot of answers, but hopefully a useful context for you to evaluate your options. Overall, I'm glad I bought it. It's a fun and nostalgic piece that is accurate and reliable. Or, if you can't make up your mind, then buy a few of them that cover all your favorite options!!
