I use and recommend the Kenai chest holster from Gunfighters, Inc, as well. I have two holsters for mine - one for N frame Smiths (all my N frames fit it) and one for Glock 20. I have carried a 629 Classic with the full length underlug barrel all day long while elk hunting without undo stress.

They also make a sweet IWB holster, with I wear every day with a G26.
