I carry a Springfield xds 3.3 45 acp. This particular gun jumps around a lot with a 45 acp so I use a heavier stainless steel recoil spring.
I used a kydex holster made by ” we plead the second” at with a 15 degree belt clip on it.
I carry this because of how slim it is and still being a 45 and its reliability Is great.
