There are several Crossbreed "type" holsters out there now. Why is that? Because it is a great design, that's why. Take your pick with regard to brand, but I've been completely satisfied with my CB, and wouldn't hesitate to buy another. For a gun the size of the Shield though, you may be happy with a Remora which is way cheaper than any of the CB type holsters. I use a Remora with my BG380, and it is perfect for that gun, so much so that I would never waste a dime on any other holster for that gun. I also have a Remora to fit my SR9c (which I have the CB for), and it works very well for that too, but for all day security and comfort, I prefer the CB for that gun due to its size and weight. The Remora is a great tuck and go option though. So even if you go with a CB, or a copy, consider getting a Remora as well since you may find it works well enough with your Shield as it does with my BG.
