Thanks goes to Mike S. (American Warrior Society) for recommending Precision Holsters and the Ultra Appendix. So far, I am very impressed with this holster. The holster tucks the pistol grip nice and close to the body but creates a little space that allows for a quick secure extraction.. The retention clips are very firm and allow a little adjustment to the angle. The hardware appears to be the same design as that used on some helmets for the NVG mounts. I have run through some draw drills and can definitely tell the difference in confidence of control. I don't have a timing device, but the proper secure hand grip prevents need to adjust as extracting the weapon up and out, so I perceive to be on target more quickly. The design of the holster took a little getting used to for wear. It does create a slightly higher signature under a light summer shirt. To explain, the weapon itself is not silhouetted, but the bulge seems a little more pronounced than some of my other holsters. This is the result of the shape that allows the more secure and confident initial grip when drawing. I switched to a standard extended magazine from an extended with +2 mag extension to reduce the butt of the mag silhouette on my side. Again, this is under a light summer button-down, and I am a little overly sensitive to printing. Since I tend to people-watch and naturally scan to see who in the area is carrying, I look at myself the same way. With normal or heavier weight clothing, I don't think it is noticeable. A pancake holster that sits lower on the belt and flatter will have a slightly lower signature, but is definitely slower and requires some grip manipulation as I bring the weapon up and out. The Ultra Appendix requires none of that, but sits a little higher. I have already recommended this holster to others and will continue to do so, while allowing friends to safely try mine and see what they think.
