FWIW, when it comes to my personal preference in self-defense J-frames a DAO Bodyguard would be a very close second to a Centennial.

And speaking of Mr. deBethencourt, you may want to contact him via snubtraining.com if you're still interested in retaining the hammer spur whether you go DAO or not. Some years ago he purchased the remaining inventory of bolt-on hammer shrouds manufactured by Waller and Sons. They bolt onto the gun's frame and give a Bodyguard-style profile. He may still have some available. It wouldn't hurt to ask.
