I have never personally owned a Seecamp but had a few friends that did. They are produced by a small Company in limited numbers. They are extremely ammo sensitive so when trying to get ammo that works reliably, you must choose it for that purpose alone and not by how effective said bullet performs. IMHO the ammo issue (at least for me) is a deal breaker as far as a Seecamp is concerned! From what I understand extra magazines must be hand fit and are a bit pricy too.
If you get the pistol to function correctly and reliably, I guess it is a viable back up gun, but IMHO a Ruger LCP Max with 10+1 or 12+1 would be a much better option and it is chambered in .380acp. The Ruger has much better sights, is very reliable out of the box and more than accurate for SD / EDC. Just my honest opinion......
