I have a #digtherig submission for you. I carry many different guns but this one the most.
1. SPRINGFIELD XD Service 4″ .40 cal with Trijicon HD night sights, TLR-1S and Hogue Grip
2. Blackpoint Tactical Wing Light Bearing Holster
3. I carry the XD in this holster because they are crafted perfectly to fit and get a positive retention “click”. There aren’t too many options for light bearing holsters for non Glocks but these holsters are nothing short of incredible. Also the leather wings keep it up against your body tight while making it extremely comfortable. A good shooting heavy polymer gun combo that doesn’t feel heavy because of the setup.
