I decided to "master" snub shooting and, this year, bought three J frames and a 686 snub. I got a little better on my own with Google and range time, but this book by Grant Cunningham has helped more than anything else. Probably not a big help to the competition shooters, but to recreational shooters like me it was money well-spent. I got the Kindle edition and found it to be well presented: [ame="http://www.amazon.com/Gun-Digest-Book-Revolver-Paperback/dp/B00843A7DA/ref=tmm_other_meta_binding_title_0?ie=UTF8&qid=1346864907&sr=1-1"]Amazon.com: Gun Digest Book of the Revolver [Paperback]: Grant Cunningham: Books@@AMEPARAM@@http://ecx.images-amazon.com/images/I/51nU%2Bby5nqL.@@AMEPARAM@@51nU%2Bby5nqL[/ame] Covers all double-action revolver shooting, not just snubs.
