I carry a Centennial, lately a model 640. In my area the biggest threat is the occasional black bear, so when I’m out hiking I load Buffalo Bore .357 instead of the usual .38 +p. That way if I do see a bear, and it doesn’t run off like 99% of them do, I can discharge my carry gun and die stone deaf (after I pee myself).

In all seriousness, I carry a Centennial because they’re what I like and what I’m most comfortable with. If I ever found a pistol that could bring me the same level of comfort in handling/use and ease of carry, I might give it a go... but for me the Centennials work so well I haven’t felt the need to look for a pistol in some time.
