I think I am already set on getting one! I want to add an old school revolver to rotate with my semi-auto for edc. I heard that Detective Specials (even the early ones) were very well built and hold up well over time. From doing some research I really want to find a 2nd series from the post-WWII era (40's-50's). Do you know how much the second series Det. Specials go for nowadays (38 special version)?I've never done either, so my opinion is certainly not definite (I do waistband carry/pocket), but as for shoulder holster, these fit perfectly. And while I've never seen one on the ankle, I know others have had success with it.
If you don't already have one though, if you fancy revolvers, I'd definitely encourage you to get one. Detective Specials (along with the lightweight variants Cobra and Agent) are great EDC guns that have been a top choice for the last 93 years, and for good reason. There are other good choices out there you might prefer, but I can guarantee it won't disappoint you.
