I was surprised when I got this because the quality and satiny feel of the bag was better than I could imagine. My full size XD with 4" barrel fits perfectly in the Large bag with a spare mag. When using the Neomag adapter I noticed that my holster with the double clips is more stable than with a single DCC Monoblock clip. The holster fits flatter with the double clips. I may take the wings off my holsters that I use in this bag since it's not necessary. I like that it is sleek and not big and bulky, it doesn't stand out like a big fanny pack would. Be careful when using the Grab velcro holster, I ripped the whole holster and firearm out when practicing and it nearly smashed my foot. Be mindful of where you place it and if you'll grab the grip or not when opening. My mistake was using my right draw hand to open it and I flicked the whole holster and gun out of the bag and onto the floor. The Neomag adapter sticks in the bag a more aggressively than the velcro holster. Not an issue with the bag at all, just my user error and learning curve.
