I got that Alien Gear, put it on, and really didn't like it. I called them up and returned it today. I dug around my holster drawer and found a Pro Carry from the previously mentioned The Holster Store. The Shield fits perfectly and rides nice and high.
BTW I shot the Shield the other day with 115 grain XTPs and it was shooting 5" low at 12 yards. It was all I had on hand at the time. I will be trying it again soon with 124 gr bullets and see what the POI is.
