Chosing a holster

I'm looking for a good in the waist apendix carry holster for my BUL sas Ulrtralight ii (compact 2011).I have been looking at something like the LAS concealment Ronin 3.0, or the Teir1 Axis Elite, which are quite a hefty purchase yet seems to be the way to go.I primarily want something with a hinge or stiching so it is more streamline, and room for an extra mag to balance the weight so my pants sit level.Also I could really use some pointers on the right clips for in the waist carry. ive seen a whole bunch of designs that claim to work with tucked in shirts and even sweat pants while running. Is investing in a belt to wear under my pants is the safest and most erganomic way to go? Or can I rely on the clips in these larger style holsters for holster retention?Thanks for the help via /r/CCW https://ift.tt/35Nlolr
