I used to have a Kahr PM9. I hated it! However, I am looking at the Judge PD. Use 5 rounds of 000 buckshot and go to the Sig if I have to.
With the Trump Card, the gun slides into a neoprene backed pouch from the top. I would consider this a holster to ensure you always have a gun. Not a quick draw. I also got this as a jogging holster. I haven't run with it yet, but I will let you know how it goes.
