I've got a box full of holsters I've tried before buying one of these for my G27. I'm in a plain clothes assignment and have been wearing one of these nearly every day for a couple years. Holster the pistol and it locks in place automatically. The draw is fast and natural. Whenever I go back to wearing duty gear, I'll be buying the duty serpa holster for my G22. I works great for me.
Pros: Great retention, light weight, fast natural draw
Cons: Doesn't make coffee
