I feel is an excellent option to have additional rounds in a small package that improves over the 380 and almost matches 9mm with great penetration. I carried a Sig 938 for years at 7+7 rounds with backup mag. I feel much better with 13 + 16 now carrying the Shield Plus. I'm hoping it catches on, am sure will have defense ammo available for a long time and I reload so practice ammo isn't a problem. BTW I did the 40 yard drill and got 19 out of 20 rounds in the silhouette. 10 supported and 10 off hand. No stress level but a capable flat shooting round.
