I carry either a 640-1 in a Mika pocket holster or a 637-2 with a bobbed hammer spur in a DeSantis Superfly holster in the front pocket of my cargo shorts or pants. If I wear jeans,(mostly in cooler weather), then the 640 or Model 60 go in a Simply Rugged Pancake owb holster. I usually have either the 640 or 637 or both on me all the time. I'm a believer in the NY reload!
